>Can you point me toward some sources that say nihilists actually believe that humans are capable of creating meaning?

That's a big part of existentialism (Sartre, Camus, etc), in which life has no inherent meaning, and it's rather empty existence, and it's up to the person to make any meaning for themselves.

Existentialism's conclusion is often nihilism: Life has no meaning. Absurdism is an extension to that: Yes, but you may create your own.
