I am the grandson of Professor Kimkeller and the author of "Washing the Dust". When my grandfather gave me the task of compiling this historical book on his deathbed, I felt that I did not have the ability and perseverance to complete this task, because I was not interested in history, and second, I was an engineering student, and I did not have any historical and cultural skills.

But grandpa's trust made it difficult for me to postpone, when I began to fully contact grandpa's historical discoveries and research results, I was impressed by grandpa's insight, speculation and unique insights, grandpa's thoughts deeply attracted me, after more than a few years of research on grandpa's manuscripts and documents, I feel that my thoughts and grandpa's thoughts have been integrated, and now when I think about the historical problems of mankind, I can no longer distinguish whether the concepts and ideas I use to analyze the problems are grandpa's or mine?

Of course, I know that to sort out the fruits of other people's labor, we must cherish the original author, maintain the original flavor of the original author's labor results, and maintain the original ideology and creative style of the original author. Therefore, if I think that Grandpa's article is flawless in grammar and expression, I basically keep Grandpa's original form entirely.

In order to make it easier for readers to better read and understand this work, I have divided the content of my grandfather's research into chapters with logical relationships and successive relationships. At the same time, I made the necessary annotations and explanations on the professional concepts and problems in the article that are difficult for readers to understand. In short, I want readers to be able to read and understand my grandfather's masterpiece easily, accurately and efficiently.

As a child, my grandfather often told me about his background, and at the beginning of the last century, my grandfather was born in a remote Zhuang mountain village on the border between China and Vietnam. At that time, the area was experiencing the expansion of French colonial rule, so all the villagers of my grandfather's village participated in the war against the French colonizers. When my grandfather was more than 3 years old, my grandfather's village was occupied and massacred by the French army, and my grandfather's parents and family all died in this military disaster.

After the disaster, the officers and soldiers of the great Chinese countries took my grandfather and other surviving villagers to Yongcheng, the capital of southwest province, for resettlement. However, after my grandfather lived in the resettlement site for a few months, the resettlement was forced to close due to the depletion of funds for the officers and soldiers and the refusal of the local yamen to accept refugees from the resettlement site, and my grandfather lived by begging in Yongcheng ever since.

When my grandfather was six or seven years old, he met the kind and loving Father Paul, who saw that my grandfather was intelligent, perceptive, and helpful, so Father Paul adopted my grandfather as his adopted son and trained my grandfather to become an archaeologist and historian.

Every time my grandfather told me about his background, he couldn't help but burst into tears! Grandpa told me that he used to be very resentful of the invaders who killed his parents and family, but after Father Paul adopted him and educated him, he understood a lot, his thinking changed drastically, he understood that human conflicts are caused by differences in ideas, and if people think of each other as one kind and one family, everyone can tolerate each other and share food and happiness with each other. After grandpa had this understanding, he had a deeper understanding of human nature, and he was more enthusiastic about the study of history, because grandpa knew that the concept of history is the most important ideological concept of mankind, and history is the identity, status and glory of the nation and the country!

From then on, my grandfather was determined to be an upright, kind, and loving person, to be a useful disseminator of civilization to mankind and society, and to work for the common well-being of mankind.

Grandpa's historical research shows that due to the difference in ideological concepts and historical concepts, it leads to the differentiation of human beings, leading to human prejudices, contradictions, and conflicts. Powerful nations have a sense of superiority, they like to divide other people's ranks, treat various groups of people and nations differently according to their ranks, discrimination and oppression inevitably lead to fierce resistance and bloody wars. Therefore, it is very important for everyone to pursue the truth and establish correct ideological and historical concepts.

In the real world, the main problem faced by human beings is the contradiction between resources and needs, no matter how hard human beings obtain, the natural and social resources obtained by human beings are always very limited, but human needs and desires are always endless and insatiable!

Therefore, conflicts and wars inevitably erupt in order to obtain resources for survival, development and enjoyment (land, rivers, forests, grasslands, population, as well as social honour, status and power, etc.). The solution to such problems is to "control the needs and share resources", but the premise is that the two sides of the conflict must agree with each other and care for each other, because no one will tolerate a dirty person, and no one will share resources and happiness with a different person. The responsibility of historical research is to establish an ideological foundation for mutual recognition and care for all mankind.

My grandfather and I both believe that there are many people in this world who care about the history, civilization and destiny of mankind as much as we do, and there are many people who are thinking about the same issues that my grandfather and I used to think about. Insight and wisdom belong to every sober-minded person, of course, when the mind is clear, anyone can feel everything in the world, understand the seven emotions and six desires of life, birth, old age, sickness and death, joys and sorrows and other helpless eternal fate, and at the same time have the feeling of "life is difficult, life is like a dream"!

Although people are like ants and fate is like grass, there are still many people who can overcome fatalism and pursue a nobler meaning and value of life. As a noble man, he must believe that outside of life and thought, there is an objective being that transcends nature and is higher than the material form, that is, the soul. The soul is the basis and master of the existence of life, consciousness and thought, and the soul is not subject to the constraints and control of the laws of nature and matter, and the soul will gain eternal life outside the natural and material world, that is, the spiritual world. If there is no soul, life is nothing but the walking dead.

In the real world, of all living beings, the human soul is the most spiritual, powerful, self-purifying and perfected soul, so the human soul is most likely to enter the spiritual world and attain eternal life and bliss!

Human beings' understanding of the soul is a kind of faith, which enriches human values and injects strong impetus into human beings' pursuit of a better life and exploration of the unknown world. Of course, for humans, the soul is still an unsolved mystery. We know that genetic DNA is the basis and basis for the production of life, that is, before there is life, DNA already exists, and the soul is the DNA of human consciousness and thought, so the soul existed before human consciousness and thought, that is, the existence of human consciousness and thought proves that the existence of the soul is a fact, not a hypothesis.

For example, the computer is the most successful and most life-characteristic equipment invented by human beings, if the computer is compared with the form of life, the soul is the software system of the computer (only the soul has the extraordinary ability to generate, learn, repair, improve and develop infinitely), and the body that carries life is the hardware system of the computer. The hardware system has material characteristics, operates according to the laws of nature, has the natural process of birth, aging, sickness and death, and if there is no maintenance and repair, the hardware system will gradually die. The software system is a series of data codes that control and run the computer, which is a stream of consciousness, thought and wisdom, because the essence of the software system is consciousness, thought and wisdom, that is, immaterial, so the software system does not have the characteristics of the material world, nor is it subject to the material world and the laws of nature, so the essence of the software system is eternal.

At the same time, we believe that the spiritual essence of consciousness, thought, and wisdom objectively exists in the universe and in the spiritual world of the universe, and that only high-level intelligent beings can effectively communicate with the spiritual world, so that the material world can create life, and let life have consciousness, thought, and wisdom. This is the best explanation of the current human beings on the issues of matter, life, consciousness, thought, and intelligence.

In the distant ancient times, human beings were in the cradle of chaotic and ignorant life, and the ancients could not have the knowledge and wisdom of today's human beings, therefore, in the process of exploring the essence and meaning of life, human beings have experienced extremely serious ideological confusion, as well as terrible conflicts between people, tribes and tribes, and races, so the antagonism and conflict of human races, mutual killing, ruthless war, social depression and decay, civilization collapse and extinction and other tragic phenomena fill every corner of human life.

At present, the world is still divided, the mind is still chaotic, mankind has come to a crossroads of life and death, mankind is in an extremely serious conflict of civilization and racial antagonism, if human beings cannot resolve this confrontation and conflict intelligently, effectively and in a timely manner, human beings and their achievements of civilization will face destruction and completely disappear!

Therefore, the purpose of this article is to discover and find the origin and homogeneity of life, race and human value, to find the power basis of human fraternity, cohesion and coexistence, to urge human beings to give up all ignorance, prejudice and stubbornness, and to let human beings concentrate their energy and wisdom on doing more meaningful and valuable things, so that human life and soul can enter a state of eternal life and bliss as soon as possible, and completely get rid of the natural fate of matter and life!

Of course, because human civilization has been accumulated for tens of thousands of years, various ideas and beliefs of human beings have been deeply rooted in groups of people and races, and human beings live in every corner of the planet, are blocked by the natural environment, and are limited by means of transportation and communication, thus intensifying the differentiation of human culture and race, and forming regional cultures and interest groups that oppose and hate each other among human beings. It is indeed very difficult to overcome these antagonisms, hatreds and conflicts at present, because it is impossible for humanity to give up these prejudices and narrow-mindedness so easily, and therefore all the stupidity and barbarism of humanity will continue. In order to change this catastrophic status quo, we must accelerate the pace of studying human thought and civilization, calmly and objectively re-examine the world, and tear down the walls that block light and truth! Only in this way will humanity be able to overcome the barriers, antagonisms and conflicts between them, and allow all mankind to work hard for a better future together.

As we all know, the difference of civilization is the root cause of the division, antagonism and struggle of human races and societies, in a world where equality, respect and fraternity are lost, wealth and status become the only criterion for measuring success in life, the nation that controls wealth and is in a dominant position will become an aristocracy, while the disadvantaged nation will be defined by the rulers as an inferior nation, and even considered a non-human or alien, in the eyes of the aristocracy they should accept the rule, enslavement and ravage of the aristocracy!

There is good and evil in the world, there is light and darkness in thought, the light mind can make people see the truth and truth, the dark mind can make people see falsehood and falsehood, and the aristocracy is often the maker of dark thoughts, and they sanctify and legitimize their rule over all mankind through myths, religions, and laws. In fact, every member of human beings has the same cognitive power, ideological power, creativity and wisdom, and the ability of everyone to feel, recognize and perceive the form and essence of things is almost the same, so any selfish practice cannot last long, deception will eventually disappear, and oppression will usher in resistance and revolution! Therefore, equality, respect and fraternity are the foundations for world peace and development and long-term coexistence of mankind.

Because of human nature, selfishness and unscrupulous means have become the regular principles and strategies of human competition today, so the antagonism and conflict of human beings today are becoming more and more serious, and if such antagonism and conflict are allowed to develop freely, all mankind will quickly enter a catastrophe of self-destruction.

Therefore, we need to reveal the nature, origin and homology of human beings and their civilizations through the study of history and culture, and re-establish the foundation of human civilization and society of racial equality, mutual love and mutual assistance, which is the common mission of historical researchers. The purpose of our work is to bring the human race to reconciliation and civilization to integration, and to make truth the common pursuit and value standard of mankind, so that only in this way can mankind have a better future, and only then can mankind and its soul achieve eternal life and bliss.

My grandfather and I both thought that thinking about the fate of mankind and studying the history of mankind was a very difficult and boring task, and that it was a thankless task, because the basic function of this work was to reveal the truth, the dark side and the obscuring side of human history, which would certainly involve the privacy, shame and fame of many ethnic groups, and would certainly challenge all secular authority and power. Although we will face many risks in the future, we will continue to move forward with this work for the benefit and well-being of all mankind.

In this article, I uphold the spirit of my grandfather's scholarship, and try my best to base myself on facts, evidence, and science, and with a serious, objective, and fair attitude and standards, to complete this historical masterpiece on the truth of the origin and evolution of human civilization.

However, due to limited knowledge and ability, my expressions, thoughts and opinions, it is impossible for us to present 100% of the real situation and truths of human beings in ancient times, but we will try to get as close as possible to these truths and truths, and provide as detailed and valuable help as possible to colleagues who like and love this work.

In any case, my grandfather and I are pure explorers, discoverers and enlightened people, and we just want to tell our readers the experiences, perceptions and discoveries we have gained in confusion, confusion, and thinking. We hope that under our initiative, more people of insight who care about the future and destiny of mankind will join our camp and work together to promote the progress of human civilization.

Friends, please follow the footsteps of an explorer of history and appreciate the twists and turns and magnificent chapters of human history!
