Are we alone in the whole universe?

Absolutely not! I mean, they found germs on Mars so that just proves that other planets are capable of sustaining life. Not only that but walk outside on a clear night and count the stars you see. Impossible? Now consider that each of those are suns in their own solar systems and that some of those might have one planet, some of them might have 100 planets. AT LEAST one of those other planets has got to have intelligent life living on it in some capacity.

I don't think so. It's very vain of humanity to think that we are the only highly intelligent creatures in the universe. At times, I am not even sure we are the most intelligent creatures on this planet. Given that we're the creatures most bent on destroying it. You don't see foxes and dolphins doing thay, do you? Just my two cents!

I highly doubt it. If you look at it from a religious way, why would a God or Gods create people on more then one planet. Well most religions believe like this. I won't name which don't incase I am wrong or leave someone out. From a scientific point of view, the fact that life spontaneously arose on earth was about a .000002% chance, so I would find it very unlikely. Of course I could be wrong.

it thrills me just thinking that there might be another earth somewhere...i mean, the universe is wide. And we don;t know exactly how BIG it really is, right? Why would we assume that we are the only ones around. Well, there were Roswell sightings and stuff but some people just want to mess up with prosthetics and everthing just to create a stir so how should we know that those sightings were fake or not. Hmmm...what if there is also another planet out there wondering if there are other beings somewhere, which means us. Yes, I think there might be in that great somewhere.
