How so?To say that God begun to exist is logically incoherent.
Let's say that an entity existed that weilded miracles, did everything your religion of choice claims God did, etc... but it began to exist at some point. Would you really say "no, that's not God?"
It's irrelevant because the Kalaam Cosmological Argument has nothing to do with God.But it is also irrelevant. For the sake of this thread we can asume that God had a cause If you whant
As far as the KCA is concerned, the universe had a cause. Whether if God had a cause or not is irelevant and beyond the scope of the KCA
I'm also interested in the other stuff that you tacked onto Kalaam in the OP. You do realize that you implied that the cause of the universe does not exist physically, right?
