Kubrik said aliens had abducted him and put him into a zoo, more or less. And we were seeing it from a perspective of a human not able to understand the reality of the zoo's alien form. And the room was created for the human. And then, just like how humans were created from monkeys, the star child was created from a human...evolution. Google it, I found his explanation for his own movie the only one worth considering.
