A former agnostic, with doubts?

[Tobie]

I'm very sceptical of the existance of nothing. Neither physics or metaphysics can even create a well defined concept of nothing, because the moment you define qualifications to it, it becomes "something" by itself.
So in my own opinion, nothing is the same as non-existence, which obviously can't happen. There is always something, even a void is something.
And the fact is, our universe can exist without the necessity of "nothing" before it/preceeding it. Space-time inflation is in itself evidence that even infinite space can be contained within a point, for instance, a black hole is much "bigger" in the inside.

I don't like to get into the semantics of nothing used by some Atheist physicists because it is misleading because as you say it's always something. Theologians seem to be in agreement that there was no time before God's act of creation, since time began at that moment. If time was created by God, there is no before the act of creation. That makes God an ontological first cause, but it doesn't mean there was a time before creation. This was even discussed by old theologians prior to the big bang theory. Now if this is true, whatever first cause in creation that started the universe has no time to precede it. That being the case...why can't this cause be the first cause as it has no time to precede it without an ontological first cause of God?

If God created the universe, it implies that he transitioned from not creating the universe, to creating the universe. A transition between two states imply some time has elapsed, so logically time was passing before the supposed creation of the universe. The only way around this I see is multiple time dimensions, but if you are going to use that as an argument, then all hope is lost for you.
