I think you mean Apes not monkeys(big difference)
Apes are creatures that include Chimps , Orangutans, Gorillas and Yes Humans Fall into this Group as well. Chimps are our closest relatives.
Monkeys are things like Spider Monkeys etc...
anyway to answer the question. If you do some looking into the fossil Record you will see there are no exact species from millions of years ago still around today.
So the Creatures that where our ancestors are no longer alive today.
As I said before Chimps are our closest relatives( we share 98% of our DNA)But this doesn't mean we evolved from Chimps.
This means Chimps and Humans share a fairly recent ancestor.
If you have any more problems just ask
We only get upset here when People tell us something like you said as proof we are wrong. Rather then simply asking like you did
