This explanation of my question had been added afterwards. My apologies to those who answered before I added it.
Atheïsts have this invalid notion that not believing in a God equals not having a religion. Their standard answer is easily disproved by creating the following equation:
Amount_of_Gods = Amount_of_Religiousness ???
That equation would state that someone with a poly-deity religion would be more religious than with 2 or only 1 God. Actualy, intuitively as i do not have any numbers on that, I would say that if I draw a graph on that, I would get a line where the overall religiousness would be the same accross any amount of Deities believed in. Or ... believing in no deity at all would make the assumption that you are not religious unlikely. The amount of religiousness should fall within the graphs expectations.
So the question would end up to be: What does define and what causes religion and believes etc and what is the (social) function of it. Is it valid to assume that its function is to span the bridge what you can't know and can't spend the effort or energy to know?
