Can you demonstrate any objective evidence for any deity YES or NO?
If you’re claiming it’s yes then please present it.
Do you accept that the KCA you cited in your OP contains several known logical fallacies YES or NO?
How can infinite regress be impossible and illogical as you claim, if a deity has always existed, as you also claim.
What objective evidence can you demonstrate for your assumption a deity is “beginning-less”?
When the KCA says in its first premise that everything that begins to exist has a cause. How many of those examples can you demonstrate any objective evidence had a supernatural cause, or that started to exist outside of the temporal condition of the physical material universe.
