Where Did the First Person Come From?

I am on a call for work and in the background I am hearing an awesome conversation between Hung and Avery. She asked where the first person in the world came from and he is trying to explain evolution. She wants to know if the monkeys were around "zillions" of years ago and if me and Hung and our parents were originally monkeys. Now she is getting blown away by the fact that the first humans didn't have TV's, iPhones, tablets, clothes, lights or money.
