> you already agreed that a creation event implies a Creator
Yes, but there's no evidence of a "creation event." The fact that the universe is here is not evidence that it was created anymore than the fact that a rock may be aesthetically pleasing means that someone made it so.
The Big Bang is a creation event. Now you don't have to subscribe to the Big Bang Theory any more than you have to marry a rock but if you do I'd expect you to be honest that the BBT is a creation event and that you'd support the pebbles that issue from your marriage to the rock.
