Prometheus represents the archetypes of the strength of the human will and defiance against authority.
According to Legend, Pandora was made out of clay as the first human by Prometheus, one of the Titans who had sided with the Olympians in the Titanomachy.
The subtitle of Frankenstein is 'The modern Prometheus'. She did this to point out a similarity between the character in her book 'Doctor Frankenstein' and the mythical Titan Prometheus. Both created a human: Prometheus from clay, Frankenstein from dead bodies.
Prometheus helped humans (he gave them the fire of the Gods). This made Zeus cross and the then punished Prometheus for doing this in a terrible way.

You're two qualifiers are mutually exclusive. Prometheus and Atlas were not human, they were Titans, and so their parents were Titans as well. They were not ancestors of humans any more than one could say that God is an ancestor of man. Prometheus CREATED man in Greek mythology. That hardly makes him an ancestor. Remember, Wikipedia is edited by everyone... and some people are idiots. For the record, though, Prometheus and Atlas were sons of Iapetos.
In Greek mythology Zeus withheld fire from mankind, but Prometheus stole it. In some stories Prometheus created man from mud. Doctor Frankenstein tried to create human life in a dead body. The parallel should be obvious.
