I'm not sure either, man. The series bible calls them Eternians, but also uses the word "human" sometimes. Also, Wiki Grayskull and He-Man.org call them just humans.

On the other hand, Eternian civilization is older than Earth's and used to be far more advanced, although that might not rule out the possibility of them being the same species.

I wish we could have definite proof one way or the other.
