See, the thing about that is, the GOL or whatever would already know the outcome of any universe made. To that end, why bother making it?
That answer's above my paygrade. Like I said, I'm a more likely a Determinism guy, and Determinism from a mundane startup[1], at that.
It
could be that the fire-and-forget God, despite being able to work out what would happen if He thought about it (as every deity worth His or Her pillar-of-salt should be able to do), hasn't cared to do so.
Alternately, the deity only gets to know what the Universe about to be started will end up like by thinking it through just before. And (similar to Next Tuesdayism) we aren't the
real Universe, but God's own internal thought processes working out the end-result of the Universe To Be. This is also compatible with the footnoted "infinite kitchen table" analogy, as every single possibility is being looked at along the way of finding the particularly fine-tuned big-bang precursor that will end up making the intended result.
Basically, this shows several of the problems of assuming an Omni-everything deity fits into any logical premise, there's just not enough 'equivalence' between our everyday concerns, abilities and motives and anything that said deity would have to work within the confines of.
You might get some sort of idea if you can ask (if you can find them, and work out a way to communicate with them) the pixelated inhabitants of a Conway's Game Of Life universe what they think you do in your spare time (apart from manage a nigh-on infinite Game Of Life universe), and see if they've got any inkling of backups. Although admittedly that depicts a universe which the creator (you) may have an infinite ability to inspect (omniscience) and even to change (omnipotence), but wouldn't be able to understand beyond "ooh, it looks like that megahumungous pattern is interacting with that other megahumungous pattern". That is perhaps another answer. Our hypothetical 'next level up' God's playing around with Game Of Life[2] could be similarly as unknowing of the chaotic future results of the simple starting conditions.
Also, don't forget that Conway-creatures can't know anything of backup and restore and run-redoing (after editing the field of play), and neither could we. They can't test for such things (unless their universe is running on a specifically buggy program version, or the Creator uses the cut'n'paste buffer too much), and neither could we.
Another Occam-worthy act of disregarding, really.
[1] Perhaps as one in any number of slightly different universes in a multiverse. Another one of my long-time analogies is that a hypothetical God's kitchen table has an infinite number of jam-jars on it, each having a different 'mix' of universe, some are spluttering and shaking and threatening to spill their contents, others are quietly changing colour, some are just sitting inert. So, if there
is a God, it's a question as to whether we're sputtering along or just sitting around like gunk, and which one of these are more likely to be taken off the table and chucked down the sink, rather than let sit there, or perhaps given the occasional stir...
[2] Having primarily talked about a God Of Logic, I can't reduce Game Of Life down to GOL, like I'd want to.
