Well even though I may have lost all credibility with the last post... here goes again.
IMO all those who have posted their opinions here have done so to their ability based on their life experiences, which probably covers about 2-3 maybe 4 generations. If I were you and had this question, I would read through history and try to find how being raised with God or a lack of God affects individuals and societies when those beliefs are implimented over many generations. I think either way the results of views are just as valid to your question, but maybe a longer time frame was something that you wouldn't have thought of. I definitely believe that a God or a lack of God would affect more than just the lives of self or of someones children. It's effects are exponential and may make some huge rifts one way or the other in the way history pans out from here.
