Drops in a Puddle

Aliens!

Do you believe in intelligent extraterrestrial life? Make your case, either for or against it.

This is something that I haven't thought a lot about, but I definitely wouldn't discount it without doing more research. I believe that anything is possible, and there is so much out there that we haven't adequately explored and know nothing about. Although I don't think there are little green men who will come and insist that we take them to our leader, I do think it's possible that intelligent extraterrestrial life exists.
