I would never be absurd enough to think we are the only life in existence. Since the size of the universe or universes are unknown, then too is the possibility of life existing beyond our known limits. To think we are the only life forms, to me is pure arrogance and narrow-minded. The possibility of other life forms need not be human or by anything we have labeled or discovered thus far. Though maybe not probable, one needs to be open to the possibility that life does exists elsewhere. If we close our minds to the possibility, we have assured ourselves of never finding any. If we do not dream and envision, we do not discover.
I never said I'm not open minded about it. I said in my opinion we are alone. We have 0 proof of any other life forms. If you compare the probability of evolution occurring and successfully making a life form to the amount of planets it makes sense that we could be alone. Also, no-one is closing their minds to possibility. There are thousands upon thousands of people trying to discover life elsewhere, and if there is life elsewhere, my guess is they would be trying to reach us. What I was trying to say earlier is simply that it seems silly to me to think that there is absolutely life elsewhere when we have 0 proof. So it goes both ways if you ask me.

To think we are not alone to me is pure arrogance and narrow-minded. (to me of course it is not, but when insulting another party when trying to make a point, even if indirectly, is a logical fallacy).
