When was it that this God of yours created the Universe?
in my opinion, the age of the earth question is moot.
No, it's a valid question to a person who is interested in science.
I was actually inquiring about the Universe, not Earth, creation. As far as I understand it, there's a gap of about 10 billion years between these two events.
Which kind of leads to another interesting (for some) question: does the Christian (or any of the other major religion) dogma recognizes that the Universe existed long before the Earth?
If it does, I wonder if there's any speculation as to what was God doing for the first 10 billion years (or whatever long is assumed to have been the interval until Earth got created) of the Universe?
Could he have played around creating life in other places? You know, kind of experimenting before finally proceeding to the Adam and Eve project? (Unlikely, I guess, since the Christians insist we are special in God's eyes. So The Man must necessarily be the one and only such creation. But then again, so was the Earth in the first iterations of the Christian dogma -- a place around which the Sun, and pretty much all the rest of the Universe, was rotating. That bit got updated once Science proved it wrong. So the safe bet will be to expect a similar update if/when Science gets proof of extra-terrestrial life.)
Or maybe he kept busy creating all the billions of billions of stars, planets, and other such cosmic objects? (Not really, I guess. He's all-powerful, so he could have created them all (except Earth, which within the working hypothesis assumes a later date creation) at the same time. No need to spend billions of years doing it.)
