Natural selection is not evolution.
That's right. It's one of the mechanisms that drives it.
Natural selection cannot lead from single cell organisms to humans.
Not on its own, certainly.
Natural selection does not lead to an increase in complexity.

Humans are made of single celled organisms, which is, when you think about it, very strong evidence that we evolved from them in itself. We are elaborate colonies of them. What's required is mutation, symbiosis, and natural selection; and lots of all three over a very long time.
It is very common for single-celled organisms to form into colonies when they can gain advantage from it.
So, in the future, think of yourself as a colony. One big happy family. And don't knock natural selection and the other mechanisms, because without them you wouldn't exist.
