Your post is very interesting, however, there are things I don't share.

It is recorded that the first human fossil is as old as 66 million years ago

66 million years ago? I think it's an exaggerated number, I thought it was around 3 million and yet the oldest writing found could be less than 15 thousand years old. There's an exaggerated discrepancy between the two dates. In just 2000 years humanity has barely reached the moon, in 66 million years they would not have gone beyond our solar system?

This is what I think has happened, somehow humanity evolves and leaves the planet, let's say for lack of resources, wars, plagues, etc. And everything resurfaces from scratch. History always tells us that it repeats itself. Who knows if we live in a perpetual cycle of evolution.

There is a possibility that technological singularity might take place between the years 2040 and 2050.

It seems to me that 20 years is not enough for a technological singularity to occur, much less from the evolution of artificial intelligence. I've been amazed at how advanced AI technology has become. I've been astonished by the go game of a human against an AI.

Maybe our behavior is not as subjective as we think and could possibly be measured mathematically and expressed in terms of probabilities.

Maybe, in the end, we are the ones who work for them and I think that a robot boss may be more humanitarian than a boss of flesh and blood ;D

Thanks for sharing :D
