Poll: Which do you believe in? (If any)

[Spacelord]

I wouldn't say 'believe', but I find life beyond Earth fairly plausible.

 

[Johnn Johnston]

I believe in aliens in the mathematical sense.
If the universe is infinitely infinite, and planets have a chance of fostering life, then there are probably aliens.

I have to agree with this. I don't believe they've visited Earth or anywhere relatively close, but the law of odds says they exist.
