I see this all the time, it's become one of those knee jerk responses, but we did infact evolve from monkeys if evolution is true.
This may seem pedantic, but by definition the common ancestor between monkeys and humans was infact a monkey, we would call it a monkey if we saw it today, it would fit all the criteria for being a monkey. it wasn't a modern one, but it was still a monkey.
The split from monkeys happened after new world and old world monkeys split, so humans are descended from old world monkeys wich would make our ancestors monkeys.
