Neanderthal tools had handles. That’s exceedingly advanced thinking.
If they were that smart 100,000 years ago, it seems to me like they would have dominated the earth long before the last 6 thousand years and there would be massive evidence of them.
I think the time frame has to be wrong. Extrapolate backwards the population growth of man and it doesn't support a 100,000 year time frame. And certainly not a 100,000 year time frame where man was highly intelligent the whole time.
