No, I don't. There is no reason to think there is life beyond Earth, as we have seen no evidence of it. No spaceships (duh! interstellar travel is impossible anywhere but in sci'fi), and no signals have ever been detected. The thingy in that Mars rock that could be the result of nano bacteria, could just as well (and more likely) be unorganic. Mars is likely dead, and likely Titan too and Europa too, and those are the main sites in the solar system.
I have never understood why some people are so into this subject. I mean, it'd be cool if the Mars "worm" (it looks like a worm!) was a real bacteria (but sad that there is no life on Mars now). But we have an abundance of others creatures right here on Earth that are way more fascinating and incredible than could ever be imagined, and that's really mind-blowing! Whenever I hear the question "are we alone?" I just wanna yell "no, you moron, we never were!" It really pisses me off how people disregard our fellow earthlings. Animals are far more fascinating than anything out there could ever be and far better and more interesting than humans. I wish it was possible to decipher the signals octopi use and try to talk to one!
Of course the way things are going , we'll soon be all alone, seeing how we wipe out species after species. I think life was a fluke. We need to make sure life stays alive. Not because Earth is alone, but because they deserve to live, they have the same right to continuing their lines.
I'm getting off topic here.
No, there is nothing that points to existence of non-Earth life forms.
And don't get me started on the UFO nuts! Morons who see all kinds of BS due to their ignorance or mental sickness. I've known one of those morons, he said he saw two. I saw them too. The first was called helicopter, the second was moon beams breaking through the clouds. OMG! Of course there is no reasoning with him. People who believe in that crap need help, it's not healthy to go around with beliefs like that. It's even less healthy for their surroundings! Being made to listen to their delusions really gets aggravating. And they say aspies go on and on about nonsense!! ! Some NTs need to look in the mirror!
Getting off topic again.
