Do you think that civilization existed on Earth before the advent of humans?

Human civilization is only a few thousand years old, and it is the most advanced intelligent creature on this earth, giving birth to a lot of splendid cultures, and after the 20th century, with the continuous development of science and technology, the living standards of human beings have been continuously improved.

I think there was a civilization on the earth before the emergence of humans, and most experimental studies have shown that dinosaurs also had intelligence, so I think there was also a civilization in the age of dinosaurs.

I think there should have been civilization on the earth before the emergence of human beings, otherwise we would not have civilization now, it should have been handed down by the older generation, I think the earth, before the emergence of human beings, there should have been civilization.

I think there was a civilization on Earth before the advent of human beings, because there are many signs that there are, and there is still a lot of scientific evidence to prove the existence of signs of civilization before.

Human beings only have a history of a few thousand years, and for the history of the earth, it is negligible, so I think that before the emergence of human beings, there were civilizations, which may have perished for various reasons, just like the extinction of dinosaurs, because in real life we will also encounter some problems that cannot be solved, and there are some remnants of ancient civilizations that we humans cannot understand.

There must be, since the birth of some people who have no quality, the earth has been seriously polluted, carbon dioxide in car exhaust, particulates, felling of trees, natural disasters, littering, garbage ponds have a foul smell.

I think there is a civilization, because we really don't know a lot of things, and we can't explain them clearly, so we still have to **.

Speaking of the earth, there was a civilization before human beings. I think this problem does exist. It is impossible for a civilization like humans to exist only on Earth.

I think there must have been farmers on the earth before the emergence of human beings, but they just said that the civilization was not very advanced.

I think that there was civilization on the earth before the emergence of human beings, otherwise when human beings appeared on the earth, the earth should not be there, if it is not civilized, the earth may be destroyed, and unlike now, we can still live a happy life on the earth.

The vast starry sky, the cycle repeats, the laws of the universe. There must be many civilizations beyond the Earth, and there are even more civilizations above the Earth. As far as the earth is concerned, there must have been a civilization, but from the analysis of the monuments left over from history, it must not have been as developed as it is today!

exists, and there is almost a dinosaur civilization.

I think there is, the water of the earth comes from the giant ice, which was artificially slowed down and stuck to the surface of the earth, and the surface of the earth was red and soft. Target. If it is not slowed down, the earth will be knocked into Shiba and rotten.

There is an extinction of the dragon in the ring, and the impact of the dead stone is also the work of the high civilization
