Some people think so.

This question has vexed physicists and astronomers for more than a Millenia. There is now a branch of theoretical astronomy devoted to this very idea. The numbers alone are staggering. For our Universe there are over a hundred million galaxies each of which has over a hundred million stars, doing the math makes overwhelming numbers for the argument for the existence of other life more than a possibility. As well as this there is the possibility that other life is not carbon based, it could be silicon based as silicon is the most abundant substance in our universe. I'd like to think we aren't alone here but proving it is a little difficult at present.

Let's do the numbers.
100,000,000,000 in a small galaxy.
1/10th of 1% of the stars have a rocky planet far enough away so that it doesn't melt everything on the surface, close enough to the star so it isn't in perpetual ice, and has a protective magnetic field. That's 100,000 potential planets.
1/10th of 1% of those planets has the right mixture of nitrogen, oxygen and other gasses; amino acids, chemicals and the like to allow breathing for life as we know it. That's 100 planets in a galaxy that is able to support like like ours.
Now recognize that there are 500,000,000,000,000 galaxies or more and you have an idea of the millions of potential planets that can suppor tlife like ours.
What about life that ISN'T like ours? Multiply that out by millions.
And, human ego believes that WE are the only sentient lifeforms in this Universe! What chutzpah! What the hell makes US so special as being the ONLY sentient beings in the Universe?

I believe that there are other forms of life, intelligent at that, but just not life as WE know it. We perceive that we are limited by space and time, but I don't believe that others may be. I also don't necessarily believe that these other forms of life are "out there" somewhere, but could be right here, living along side us, simply in an alternate dimension.

I honestly believe that we are not alone, why should we be so arrogant to even assume we are. With all the stars in the cosmos there has to be planets that are earth like, plus life can take many different forms on many different planets.

We probably are not alone but the other forms of life would be very unlike us, if they would be carbon based like us at all. the chances of them being anything like us are slim

Well, the only ones who DON'T believe in it are the same idiots who think that the universe was created solely for us humans. *rolls eyes* It's quite pretentious to assume that we are the only form of life there is.

There are galaxies 50 Billion Light Years away.
If you were traveling at the speed of light it would take 50 billion years to get there. There has to be something else out there.

there is no proof of other intelligent life any where in the iniverse except on earth. but there are billions of galaxy out there. I would like to think that we are not the only source iof life there is, i hope we are not.
