Wow... good reading here. I should seriously set aside more time to read and reflect on these things.
I guess I should say, I believe more in the possibility in that there was a person named Jesus Christ as it is possible there was a person who lived at the time he is said to have, that was named Jesus Christ, that was a carpenter. What happened after this, I don't know. I tend to believe that many stories were made because many people think they need to believe that there is something more out there than what they see and know. These stories evolved and were followed as a reason for being.
As for something else being out there... as in other life forms in what we call the universe... I think it is pretty selfish to think we would be the only living beings in this mass of solar systems.
