Okay, I think we are arguing the same point. I will be more clear about my stance. I believe that if we discover life on another planet it will change many philosophies but destroy none. Many people will be forced to change their view of the meaning of life but Christianity as a whole will not at all be affected. Is this your point too?

no . . . well, partially. some people will adapt, it is in human nature to hold onto your beliefs. some will completely abandon it, and in severe cases some might go insane with denial.

Unfortunately I think you are right.
