But just because some mammal or another evolves into a sapient doesn't make that sapient "human" in the way we're using the word in this context.
The path from the little critters that existed at the time of the dinosaurs to H. sapiens today is very specific, and we know of at least 2 or 3 bottleneck events in our recent evolutionary history. The idea that our species could have arisen anyway is beyond absurd. The universe does not work in this fashion.
Ok, so it's your theory that mammals could continue to evolve in a completely different direction, with different evolutionary pressures for say 45 or 55 million years, but then all of the sudden veer off in a wild direction where they follow pretty much the same exact path that early human ancestors followed...
Such that, at the end of it all, we have something that either or both looks like an anatomically modern human and would (hypothetically) be able to have fertile offspring with a H. sapiens human?
Because, I have to tell you, that's pretty batshit.
