obviously tongue-in-cheek

Humans haven’t been around for millions of years though. Or is that part of the cheekiness?

It depends on what you mean by human. Homo sapians emerged 200k or 300k years ago. But the genus goes back further. Homo habilis goes back 2.4M years.

Homo Abilis, 2 million years ago, used stone tools.

Yes it's not the modern human but I think that's close enough.
