There IS proof of alien life outside our planet; even if it's only bacteriological as far as we know.
I don't know if we are the only intelligent beings in the entire universe, in the same way as I can't be sure about the existence of one or several gods whom might have create us.
Personally, I like to think that we are not alone; that there are other worlds, and countless possibilities for different kinds of lifes and thoughts. Anyway, I'm not so conceited to claim "this is the way it's supposed to be" without direct evidence.
It isn't conclusive proof, but you would be referring to NASA's investigation of Martian meteors, I'm guessing.
They didn't actually find life, explicitly, but they found certain evidence thereof.
Planetary scientist Dr. David McKay said in, I believe, 1996, "There is not any one finding that leads us to believe that this is evidence of past life on Mars. Rather, it is a combination of many things that we have found. They include Stanford's detection of an apparently unique pattern of organic molecules, carbon compounds that are the basis of life. We also found several unusual mineral phases that are known products of primitive microscopic organisms on Earth. Structures that could be microscopic fossils seem to support all of this. The relationship of all of these things in terms of location - within a few hundred thousandths of an inch of one another - is the most compelling evidence."
Dr. Everett Gibson, of the same team, said, "For two years, we have applied state-of-the-art technology to perform these analyses, and we believe we have found quite reasonable evidence of past life on Mars. We don't claim that we have conclusively proven it. We are putting this evidence out to the scientific community for other investigators to verify, enhance, attack -- disprove if they can -- as part of the scientific process. Then, within a year or two, we hope to resolve the question one way or the other."
Then in 2002, NASA released a statement in which they said a team of researchers, using the Magnetite Assay for Biogenicity (MAB) as a biosignature, concluded that, "one-quarter of the magnetite crystals embedded in the carbonates in Martian meteorite ALH84001 require the intervention of biology to explain their presence," according the lead researcher Kathie Thomas-Keprta. Basically, on earth, we would assume magnetotactic bacteria caused them, so we assume that they at one time existed on Mars.
There is, however NO proof that life exists NOW.
These studies suggest that extremely primitive life may have existed on Mars over 3 billion years ago.
tl;dr, some scientist dudes found some shit that made them lol and say bacteria and shit existed on Mars a long ass time ago, lawl.
