17,000 years ago! That's before the time of what we have called "the flood!"
We have begun to learn learn a good bit more of those times. Little evidence remains of those times, but we begin to gather more. A big supposition of ours is that there humans here then as there are humans here now. There is no proof of that yet, but there is evidence and reason, that helps me to believe that it is a good guess, if not a very exact one.
This video shows an attempt to learn realities of our past. We do seem to be learning of our doings as long ago as 17,000 years. It now seems that the belief that our ancestors existed then is very reasonable. This video demonstrates ways in which we can now consider some details of that existence. Evidence and reason are two good tools of ours.
