Jar,
<<Once premise 1 is accepted, I submit that it is really not that difficult to make progress quickly in determining the nature of God. We are not in the dark since a God who exists and who encompasses the "good" things we know will have left us plenty of clues to help us out.>>
I don't really want to get into a debate about this, but it has always startled me (at least in my adult, more reflective years) that mortal, fallible, generally silly and short-sighted beings such as humans can posit the existence of this ubiquitous, omniscient creature completely different from what we are and claim any "knowledge" of "him" (it, her, whatever) at all. It seems to me to be a kind of unconscious hybris. Especially when it happens so frequently that those claiming most loudly knowledge about this purported "being" invariably want something from you, either money or your "allegiance" or for you to behave in a certain way and not any other.
