Question from an actual kid, though she was eight, not five. Hopefully there’s an explanation more detailed than just “no” I can pass on to her.

There are a lot of good, informed, Like you’re five answers here, but a lot of what it really boils down to is when you decide we stopped being neanderthals and *homo erectus*.

The estimates out there range from 10,000 years ago all the way to 400,000 years ago.
