How can God be male or female? If you think about it, God wasn't reproduced by anything, it just always was.

I don't think we can reasonably assume that God looks like us either, especially since he is able to appear in different forms. It logically follows that God appeared in the form of a human to relate and make sense to humans. Imagine, hypothetically, that advanced organisms exist on other planets. They likely wouldn't look like humans, so naturally, God would not appear to them as a human, but in the form of... Whatever species they are.

If God exists, it's some shapeshifter thing that probably doesn't have gender, and we can't even begin to understand what God really is aside from what it did for us as laid out in the bible.
