I am an orthodox Christian, ask me a question!

[Darwinian]

God does not "come into existence", a temporal designation that doesn't apply to a transcendent being, so your question is fallacious at it's root.

Therefore, your entire argument is based on the existence of a realm that lies outside all the known laws of space and time. A realm that cannot be examined or investigated or be subjected to any known tests or experiments. A realm that cannot, by universal standards, exist as the very nature of existence requires a temporal dimension.
