What evidence can prove the existence of prehistoric civilizations?

People are born with an innate curiosity and fear of the unknown. Where do we come from, where do we go, what is the ultimate secret of life, and what kind of existence does civilization exist? Philosophy has given a lot, since the moment human beings first thought, but we still know very little.

The accumulation of time seems to let us discover some clues in the past, true or false, but they do exist, and these unproven evidences are fine.

Note: I often read a magazine in high school, and there are often two sentences printed on the cover: We strive to explore in unknown areas, and rediscover in known areas.
This was written a year ago, because it is more messy than the “patchwork” (some are from some magazines, and some are my own ideas), so there are a lot of rigorous places, but this is not a scientific paper, just a point of view, everyone You don’t need to be too demanding, you can read it as a history or science fiction book. However, it is difficult to prove that what I said is all wrong. First of all, most of the scientific discoveries in this are true, but the interpretation is relatively “sci-fi”. Secondly, there are indeed many unsolved problems in the theory of evolution, such as the Cambrian life explosion. Although there are some corresponding explanations, There are also different opinions, and there is no unified answer. For another example, there are fossils of “apes” and humans, but the transition form from ape to man is missing. On this point, there is also a relatively new saying that it is a transitional type. Because they are in the water for a short period of time, there are not too many fossils left. The main reason is as follows: Primates have exuberant hairs and tails, but humans do not have them when they grow up. Instead, they are smoother like aquatic mammals. People’s body surface, and people have a natural love for water, children especially like to play in water…
Finally, there is no “harm” if you think about the interpretation of Mayan civilization!
