Good exists - a Catholic comments

[LinuxGal]

The first moment of the Big Bang was an event (a point in space and time).

The cause of any event must exist on or within the past light-cone of that event.

If God exists outside time, then he does not exist on or within the past light-cone of the Big Bang.

Therefore God is not the cause of the Big Bang.

So who or what was?

The event of the Big Bang has no past light cone. It's a singularity. Time begins there, just as England begins at Land's End.  So the Big Bang can have no preceding cause.
