I believe in aliens because they can be explained.

"Anal Probing Angels" sounds like a good name for a Porno.

I can't vote, cause my beliefs are not represented. I don't believe in either, but I am not undecided nor ambivalent. I do not feel that either exist outside of one's imagination. Of course, I could be wrong (I will maintain a scientific outlook) and I will not pass judgement on anyone that does believe in either, but I strongly believe that they do not exist.

I am undecided or ambivalent.

I don't know if they exist, but I'll need some proof before I'll believe in both of them. But I'm not going to disbelieve in them because there's no proof that they don't exist.
