More likely than not I would say.

To think that we are the only planet that can sustain life in our solar system is just ridiculous and self centered.

Nor will I care. Interplanetary asshole is just another asshole from a different planet. Very funny of "non believers" wanting to believe in aliens... funny, funny.

I hope there is life 'out there', but we are here, in this forum, basically because there is a LACK of CONCRETE EVIDENCE that 'god' exists.
There is also a lack of concrete evidence that aliens exist.
Is it fair to believe in one, but not the other, based on the preponderance of evidence?

I think there very probably is. I do hope there is something, a simple algae or amoeba, just something right here in our solar system. Sadly I suspect we may never meet whatever life is out there in my lifetime.

It would be arrogance on the part of earth's inhabitants to presume to be the only existing life! It is interesting to contemplate the possibilities of other life forms, yet I find myself cautiously interested in actually finding out about other beings. Well, if they were to visit our planet; what if they were not friendly, and having wasted their own resources were looking to replace their world with ours. Hmm, then again, if we don't work harder to care for our own planet, no other beings would want our planet!

Yes, I believe there must be other life out there. Our only concept of life is carbon based organisms. What if there is life out there that we don't identify as life? What if we've already come in contact with it but didn't recognize it as life?

Yes! Statistically it's just so probable. There are still unknown species of fish or vegetation in deep oceans on our own planet, so why wouldn't they exist in this immense universe? Fascinating indeed.
