However, it is just as valid of a belief to take an atheistic position and believe the universe is eternal. We cannot observe what happened at or before the big bang, but there are scientific theories, compatible with the known universe, which posit an infinite cyclic universe of big bangs and big crunches.
First, from what we know of this universe, it "began at a point in time" (realizing of course that time came into being simultaneously). So in regards to what we know now to be true, not just a theory, it is more rational to believe in a Creator rather believe the universe is eternal.
Second, if the universe does collapse, or crunch, and then bang again to form a universe, it is not the same universe, so it is again irrational to say that the universe is eternal.
Third, even if there is an infinite cycle of crunches and big bangs, this only delays the problem, not solves it.

An atheist could just as validly posit the existence of a mindless, eternal medium governed by laws which cause the spontaneous generation of 4D spacetime universes such as the one we live in. There is no logical necessity for the First Cause to be a personal entity.
Where do the laws come from? To say that certain laws that govern the universe have always just existed, is more irrational than believing in an omniscient, omnipotent being who created the universe. Laws require a law giver, they cannot just form themselves.

I think Cubedbee would agree with me in saying that arguments like the God of the Gaps, Causality, and Intelligent Design arguments are bad ways of showing God exists, or that he doesn't exist.
But of course these arguments are not meant to prove that God exists, only that it is plausible and likely that he exists; that it is more rational to conclude that he exists than that he doesn't exist.

2. Causality - another bad argument if one means that positing a "god" solves the "first cause" problem. I think, such a proposition just shifts the "target of explanation" to the "god" in question - how do we account for God's existence?
Then you have misunderstood the argument. The argument's purpose is to directly answer the question "how do we account for God's existence?". And it does a decent job of answering. I think it is a fairly strong argument.
