FM, you've hit it squarely on the head. A person who believes in the Abrahamic concept of "God" relies on subjective texts written 2000+ years ago by people we don't know, writing about events we generally cannot verify. Even as a "belief" it's quite shaky, let alone as science.
And then this "uncaused cause" is even shakier yet because it defies what we witness every day (cause and effect), plus who was at the BB or before to verify what happened? How could one possibly know one god did it unless they were there to witness it themselves?
So, it begs the question why do we supposedly have to believe in a theistic cause in the first place, especially since the cosmologists and physicists hypothesize that sub-atomic particles that make up all energy and matter could have always existed, and most cosmologists lean in this direction?
And finally, in religious matters, many of us rely on theologians for help because this is their field, but it seems logical to me at least that we should rely mostly on research scientists when it comes to the issue of the BB. If I need a root canal, I don't go to a lawyer's office; and if I need legal advice, I don't go to a dentist's office.
Anyhow, your post was well said, imo.
