Disproving Odin - An Experiment in arguing with a theist with Theist logic

[Angrboda]

I'll give you "enormously powerful"... that's the only property required of such a force.

Taking all this into account, you could rephrase the premise like this:

4. To stop an infinite regress of causes, the cause of the universe (or it's predecessor) is an uncaused, enormously powerful force.

Since the sum total of energy in the universe is thought to be close to zero, it follows that it doesn't actually require a very powerful force. But relative to what are we actually measuring this against? It seems that the "power" required to create a universe is essentially a dimensionless measure, as we have nothing to compare it against. It takes as much as it takes, and that's about all we can conclude about it.

(Which oddly enough leaves us with only "uncaused" as a qualification. But then, that seems to follow tautologically, so it doesn't seem as if we've demonstrated anything more than our initial assumption that caused things can't be the cause.)
