I find it mind-boggling that six people so far have the absolute omniscient certainty to vote "no", as if they've insight into something we don't.
Depending on your definition of life, it could range from proteins floating in a puddle under a distant sun, to locomotive animals, to plant-like concepts, to things we've never even imagined! While I would definitely hold a great deal of skepticism about claims to have been abducted by the greys, or that the reptilians are secretly controlling the world, I'd say it's incredibly arrogant to assume that nowhere else have amino acids linked together, and replicated themselves.
As for intelligence...well, that's a different matter entirely. Extraterrestrial intelligence may also take different forms than what we're used to, or similar adaptive pressures may have driven it the "tool user" route like us. We can't say with anywhere near certainty until either we meet them, or we better understand how such pressures affect development.
