P.S.: Dearest sister in Christ, just one further observation. Here you give a splendid illustration of the problem of Infinite Regression. I understand that, in mathematics, if one obtains an infinite regression as a result, this is usually a sign that there is something dreadfully "wrong" about one's equations....
Aristotle proposed that nothing could be either knowable or meaningful under a universal condition of infinite causal regression. Which is probably why he introduced the idea of a primal First Cause — the Unmoved Mover which causes the Cosmos to exist. He argued that, among other things, reason itself would be impossible absent a first-cause Origin of the Cosmos.
What the Darwinists consistently avoid is the FACT that at some point there HAD TO BE a Creator, even if that Creator did nothing more than "get the ball rolling."
The proponents of the "big bang" theory cannot answer the fact that the particles that eventually combined to form atom DID NOT CREATE THEMSELVES. As you noted with the infinite regression fallacy, these particles could not have emanated from nothing.
Truly, infinite regression of causes are impossible. To visualize why this is so, consider dominoes. A domino falling over was hit a previous domino that fell over and so on. If there were no starting domino which fell (no first cause) then no dominoes would have fallen. But we see fallen dominoes therefore there was a first cause.
