Religious vs. Scientific Cosmology

Naturally, the religious (and since this is the U.S., the only possible religion this could refer to is Catholicism - hopefully someone caught on to the sarcasm) cosmological theory is that God created everything. The assumptions here are that no other divine beings exist outside of God, that nothing created God, that God always existed, that God has infinite power, that God planned this, that God cares, that God made it with a design.

Scientific cosmology is a bit more varied. Variations aside, the most popular and, therefore, "correct" theory is the Big Bang theory. The assumptions here is that we are assuming the universe is not rounded, that there is a center within "seeing" distance of the earth, that this is the first (and only) incarnation of the universe, that the universe hasn't always existed in time as we know it and care to about it as, that God didn't create it, (from Stephen King) that this universe isn't actually a blade of grass in another universe, that this is all real (a la Matrix).

I'd like to postulate a much question than those that science and religion posit; does it matter how we got here?

If science is correct, there is, at this point in "time," no means to stop our absorption back into the single, infinitely dense point that the universe was originally concentrated in.

If religion is correct and the existence of God is proven beyond correlation (correlation is not causation), then people will only believe in God because they are scared. That's not truly belief. That's knowing. God asks us to believe in him, not know he is there. Those that "know" God, sin.

No matter what, it doesn't really matter. Not truly. We can't see into the future, we don't know what's going to happen, we don't know which divine beings exist and what they are like.

For all we know, no one has yet to believe in the correct divine being; conversely, we could all be believing in the correct divine being (even atheists and agnostics, in a way) and that prosecuting the others will cause us to go to Hell, Hades or whatever variation. That is, of course, assuming there is a negative or positive place to go when you die instead of just being in the ground and there being nothing beyond that. It's irrelevant, it doesn't change anything, from people's true beliefs to preventions.

Of course, some will argue along the lines that "since we know how we got here, we can prevent our absorption back into the 'infinitely' dense point from which we spawned/other universe/other dimension/whatever." A simple question - why are we still in this universe? If we can stop the absorption, then we should be able to create an expansion, meaning we could create another universe, one in which we could live in just in case we fail to stop the absorption. Besides, we know how humans are born, but we have no idea how to achieve immortality (and by immortality, I mean living forever in the flesh, not in memories or deeds done or other such things).
