"And if early humans evolved from apes, why are there still apes? Why did they not evolve even slightly over the millions of years it supposedly took humans to evolve? "
A news species that evolves does not mean that other species cease to exist. It is not a zero-sum game. In reality, today's apes and humans have evolved to the state they are in from a common ancestor species.
The apes evolved in one direction, and humans evolved in another. We did not evolve from any existing ape species. We are on separate evolutionary tracks, although we come from a common prior species.
By many definitions, human beings are just another ape, anyhow. Chimps, Gorillas, Humans, Orangutans...we're all in the same family. We do different things, and are adapted for a different environment. Otherwise, we're all pretty darned similar, as a trip to any primate house in any zoo will demonstrate rather quickly.
We're not better than the other apes...just different.
*And God became ape, dittoes.
