a hundred thousand years is a lot, thie thing is that the human mind is not able to understand quickly huge numbers when talking about stuff like money or years.
what i mean with this is like if you take into account that the neanderthals got extinguished 40000 years ago, and that current life expentancy (which is really high in comparison to like 100 years ago) is 85 years, you get the fact that 470 generations of humans have passed since then, but, again, with how lower the life expentancy was back then, there's probably more.
we only get to see people who are 2 generations older during most of our life. sometimes 3, but that is really rare.
but yea i know that your main point is that the other homos (hehe) were ugly and you are so right
