Only 250 million years ago (about 1/18th of earths history) there

Both mass extinctions gave evolution a major boost be opening new
ecological niches for surviving animals to evolve into.
Would it be
totally unreasonable to think that 1 billion years ago there was
human society?
Of course it would be totally unreasonable. 1,000,000,000 years ago
the highest life forms had only just evolved multicellularity.
Maybe even as advanced as we are? How much do we know about
the earth 1b years ago,
Science.
or life forms of 1b years ago?
I think you need an education.
Why, because I'm not eduated in evolution? I was just pointing out
that the earth can go from small forms of life to a modern
technologicacl socciety (say fire and agriculture) in 250 million
years. Since I don't kown anything about earths distanct past I was
simply asking.
OK, but your questions show that you really have an appalling knowledge of
anthropology and paleontology. As Ye Olde One points out, for most of
earth's history, life was dominated by unicellular organisms and
multicellular organisms did not start to flourish until about a billion
years ago. It would take quite a leap of imagination to consider that these
organisms could have had anything approaching even a primitive society by
human standards.
H. sapiens did not appear on the scene until at most only a few hundred
thousand years ago and human societies did not approach anything like a
civilization until perhaps 10,000 years ago. And there is no way that any
society, since vanished, approached the sophistication of ancient Rome, let
alone modern society.
