The following is based on a few assumptions, the most basic of which is the third, upon which the others are based on.
1. God created the universe
2. God exists
3. The Bible is fact

As far as I see it, the Bible is historically fact, which has been proven by written histories and ruins that can be dated to the same dates as the Bible goes to. Given the fact that historically the Bible is accurate, it would seem to me that taking the entire Bible as fact makes the most sense since God is the same throughout the entirety, and doesn't change from book to book or chapter to chapter as must be the case if there isn't one power behind the entire thing. Anyone who's read a series written by one author, and then taken up by another author after the first one's death changes. And they are attempting with all their intelect to stay true to the original, but it just doesn't happen. It just doesn't seem like the Bible would stand up to the scrutiney it's been put to if it had fictions and un-truths in it. Having made some sort of argument for my third assumption, the second and first have to also be true as far as I see it, so I can get down to the nitty gritty.

If you ask where God came from, you also have to ask when God came into being, or existence. Everything created has a definate starting and ending point, as most any physicist these days will tell you. This was an argued point for many years among physicists as they liked the idea of an eternal universe where we are just one tiny speck in the face of it all, but Stephen Hawking and one of his comrades a number of years ago managed to prove to them that the universe had a definate starting point, and will most likely have an ending point when all the energies at work have fizzled out. So if we can figure out when God came into existence figuring out why should be a fairly simple matter.

Anyway, if we take the first two assumptions, then we start finding problems with God being created. First and foremost in my mind is the fact that if God created the universe, then he also created time, which makes the point of when God was moot, since he was before time began. My ability to explain what's going through my head at this point starts to become fuzzy, but suffice it to say it's really cool and works from all angles aproached from, it's probably genius and world shattering stuff, but since I can't verbalize it the world will have to wait for someone who can. But the problem with God being made as far as I can see is that there's no time when he could have been made. The best bet for him being made would be at the creation of the universe, as that's the earliest point in time when he could have, but he created the universe, so he had to be around before then.

We'll see if I can expound on this a little better after I've been awake a little longer, maybe I should go to bed and see if that makes some more smarts come out.

1 Timothy 6:20-21
Timothy, guard what has been entrusted to your care. Turn away from godless chatter and the opposing ideas of what is falsely called knowledge, which some have professed and in so doing have wandered from the faith. Grace be with you.
