Absolutely, as long as they are not condesending or done with a misplaced air of intellectual superiority.
PSac, just because you aren't an intellectually inferior believer doesn't mean the VAST majority of believers aren't either. You're a smart enough guy to look around you and see what belief and believers have done to this world. Don't take it personally when people with unfounded views are treated condescendingly. Sure it is a generalization and a stereotype but for the most part it fits.
No one alive can state for a certainty that God exists.
By the same token, no one alive can state for a certainty that God does not exist.
We can BELIEVE either one , but we cannot PROVE either one.
We can view the same evidence, or lack of it, and come to different conclusions about God's existence.
No you can't. There is no evidence that God exists. Beliefs are not conclusions.
Why is it so difficult for so many believers to admit that they simply BELIEVE? Why try to convince others that there is evidential support for their belief, or that they have examined the universe and come to the conclusion that they believe? It is NOT possible to examine the evidence and come to ANY thoughts on an invisible sky-person WITHOUT PRECONCEPTION THAT SUCH A BEING EXISTS.
