What?
Homo sapiens are distinct from Homo Erectus. They are an entirely different species. Species evolve from species, species don't evolve into species. There has never been a homo sapien that "was" a homo erectus. The first homo sapien was born a homo sapien.
A chickadee was never a Tyrannosaurus Rex.
Dinosaurs aren't a species, ("Tyrannosaurus rex" is a species) they're a clade... A clade which includes birds.
So to reiterate:
Incorrect: Homo sapiens landed on the moon. Therefore, Homo erectus, an early ancestor of homo sapiens, landed on the moon.
Correct: Homo sapiens landed on the moon. Therefore, hominids have landed on the moon.
Saying birds aren't dinosaurs is like saying hominids aren't primates.
