Which GOD ?.... This world is crawling with Gods..
Some Jews have a few, "christians(whatever that means)" have many, and everyone else has their own designer "Gods"..
Even what a "God" is supposed to be; is a nebulous concept..
A better question is I think.. (A)Do people want to know who God is.?. -OR- (B)Do people want some "God" to know who THEY are.?. I think "B" is the answer.. In my experience most could care less about "God's" problems and are concerned with whether "God" cares about "their" problems.. Basically its all about them not "God" at all..
"God" is seems has few friends.. much like a lottery winner..
"God" it seems is either like Santa Claus -OR- like Alex Trebek.. i.e. Pose the answer as a question, correctly and you get a cookie..
Nah!.. Which God is a better question, before you even get to the Darwin thingy... That question answered: pretty much answers the other questions too... I would say..
And you are ill-informed.
