Scientist are discovering new and weird shit on our own planet all the time.
Just imagine the kind of life that we might find here, on Saturn's moon Enceledus with a liquid ocean under a frozen surface-
Or here, in a similar situation under the frozen surface of Jupiter's moon Europa -
Or even on Titan, another moon of Saturn that has an atmosphere thicker than earth's and all sorts of exotic proto-biologocal processes possible.
I believe that as we continue to send out human and robotic explorers, we will find that life is everywhere. And that raises very intriguing possibilities about the odds of intelligent life developing elsewhere.
All you folks out there with a bug up your ass about "cultural diversity" who get pissed off when you have to select English as your preferred language...you ain't seen shit.
Someday you'll be embracing your Muslim enemies and saying, hey, at least they're human. They come from the same plaet I do and that makes us brothers.
