We have no proof that there could not and are not on any life on other planets. Plus there a numerious of sighting to UFOs.

Does this mean numerous sightings of UFOs?
I assume it does.
So what?
Numerous people could tell me the pope is a muslim - doesn't make it true.
There are some pretty convincing statistics on mass hysteria movements that suggest that this obsession with alien abductions and aliens arriving in UFOs is probably to the 20th/21st centuries what witch hunts were to the 16th/17th centuries - lots of people making noise, not much substance.
Carl Sagan wrote some nice stuff on this - you should check it out: The Demon Haunted World is a good place to start.
If there are aliens I would assume they would be illegal. Should we build some kind of wall to keep them out? No silly looking, green, lovable ET is going to take my job away!!!!! Next thing you know they will be transporting all of our jobs to other planets. It's a conspiracy I tell ya!!!!!!!!
Since the question is if I believe there are aliens on other planets, I'd have to say yes. Ask me if I know, and the answer is of course: I don't know.
I don't think it's completely unfounded to say that the probability of aliens on other planets is very high based on the sheer number of planets with suitable conditions there must be out there. Someone made a silly argument about so many people on this planet that there must be another me out there somewhere. That argument doesn't work since there can always be just one me (or I'm suffering from a multiple personality disorder, in which case that some other me is not somewhere out there). It is not unlikely that there is someone out there like me (same opinions, same appearance or whatever).
Unlike belief in a single God (or gods at all for that matter), the probability that there exists other living, sentient beings much like ourselves on some planets out there is rather high (from our perspective). We can observe a lot of the building blocks needed to sustain and allow life to grow. So, I believe in aliens. I don't know they exist. And I somehow doubt that they've been to earth, but I wouldn't dispute that possibility too much either.

Well, the chances of us being the only life in the universe are slim, but that dosen't mean that we're not alone. I really don't care about the issue. If they're there, then they're there. If no, then no.
Seriously, if the anthropic theory of the universe is correct, we are here because the universe was fine tuned to allow life to happen, therefore we would not be alone because we would not be unique in living on the only planet hospitable to life. It is beginning to look a lot more like we don't have to even leave the solar system to find alien life and the funny part is with all the bombardments all the planets received early on in the formation of the solar system it might be found hundreds of years from now if the space program continues to expand, that whatever planet life started on in our solar system, it got blasted by asteroids, comets, and meteroids powerful enough to send bio material to the rest of the solar system, inner system at least. That would mean we would have a real puzzle on our hands in another hundred years when we get to mars, scouting the atmosphere of venus, etc., and say, finding life and they ALL were based on the same kind of DNA code we find here. On venus, I am talking about the recent finding that there are anomolies in the UV spectrum suggesting the possiblity of microbes in the upper atmoshere on venus that is in a range of temps and contains the nutrients needed for life and there may be microbes there. So the next hundred years are going to be exciting ones for life science for sure. It could be that if life is found on Mars for instance, asteroids or comets hitting the surface of mars blasted microbes that ended up here on earth and started life here so we may be martians! Or vice versa. Time will tell if we don't screw up so bad we are forced to give up the space program.
