I know this is an old question, but does anyone have any new ideas on it?
One argument is that God has always existed, but why should anything exist at all? How could this happen?
Another approach is that God (and possibly God's creator(s)) came into being at some point, before He then created the universe. But how could there to be a point at which something began to exist, where before there was nothing? Scientists argue that something can come out of nothing, and that this happened at Big Bang. Some of them say 'Nothing is an unstable state - it is not surprising that something has emerged'. However their 'nothing' is a particular condition of space-time, under various science laws that already exist; why should there even be physics laws?
I'd be interested if anyone had any thoughts? Thank you.
