One of the main things people get confused by is that humans and monkeys were basically the same during evolution. Actually, humans and monkeys have a common ancestor. So theoretically, monkeys cannot become humans. As well, it hasn't been scientifically proven that evolution actually happened, it's just a theory.
Lots of people have jars of peanut butter sitting on shelves. Not one of them has evolved into anything other than peanut butter. That does not mean they never will, but so far there are absolutely no observations supporting the theory. Every bit of evidence offered so far has turned out to be a hoax.
