If Darwin's theory is correct then world would be over populated cause we are from apes plz explain?

Darwin's theory is incorrect, therefore this isn't an issue.
God created the world in six literal days and the earth is not billions of years old, in fact it is only about six thousand years old. People did not evolve from apes, or any other species for that matter, we are completely separate from animals; no relation whatsoever. Evolution is actually impossible, whether you would like to believe that or not. What Evolutionists use as evidence is the same things Creationists use as evidence, only one of the two can be correct, take the Grand Canyon for instance, the rock layers there were not laid over millions of years they were laid relatively quickly, when God flooded the earth the rock was quickly picked up and carried there, and as a result we find billions of dead things in layers of rock, those fossils were formed fast when the flood waters swept rock over creatures and they died there, quickly becoming fossilized. If they had been fossilized over millions of years their bones would have decomposed. I won't make this too long but if you have more questions feel free to ask me or visit AnswersInGenesis.com there is plenty more evidence for creation than what I just presented to you here.
