For one, there’s multiple types of monkeys. For two, it’s entirely possible that the original monkeys had fragmented- some remained monkey, and some turned into humans
However I’m Christian and believe in God guided evolution. It didn’t occur by random chance- that’s scientifically impossible (or at the least astronomically unlikely) due to irreducible complexity of organisms, the complexity of DNA/RNA encoding, the origin of the first life having never been recreated in a lab, the perfection needed in a solar system and planet for life to occur, etc. Everything about humanity screams “Design”.
