Sam Harris raises the old village atheist query “What caused God?”. As he puts it: “the notion of a creator poses an immediate problem of an infinite regress. If God created the universe, what created God? To say that God, by definition, is uncreated simply begs the question.”
Sorry, but that’s like saying “if you think a boat will hold you up on water then what holds the boat up? To say that a boat, by definition, ‘floats’ simply begs the question.”
Nah, it don’t work that way: boats float and hold up things that don’t. That’s what it is to be a boat.
And God necessarily exists and sustains things in existence that don’t. That’s what it is to be God.
