Atheists, what are the most convincing theist arguments you heard of?

[masterofpuppets]

The most convincing argument I have come across is the Kalam Cosmological Argument. Although its premises have not been demonstrated to be true, I can accept that "the universe must have a cause" is not a completely unfounded assertion. As far as we can tell, all events within our universe are government by cause and effect. The reason I do not accept the argument is that it assumes that (a) therefore the universe itself must have a cause, even though cause and effect is a property that can only be demonstrated to apply WITHIN our universe, and (b) that this cause MUST be a deity, when for all we know it could be a wormhole that leads to another universe.

Also, the premise that "the universe had a beginning" is not entirely correct. While the Universe had a TEMPORAL beginning, we cannot deduce that therefore the Universe had an absolute beginning. The Big Bang could have just been some kind of transition of the Universe. "Vacuum metastability event" is actually the term cosmologists use to describe a kind of transition that fundamentally alters the Universe, which results in drastic changes in the foundations of physical laws/constants, spacetime and matter.
