We always observe cause and effect in nature. There are trillions of cause and effects in nature and no hard evidence of something from nothing. This is an overwhelming preponderance of evidence beyond a reasonable doubt that nature always has a cause so it can't come from non-existence which is silly anyway.

But neither can the universe or nature always exist because if it did, you would have had by that definition an eternity to come into being before now so you should have already happened. And you would never have existed because a past eternity would go on for eternity, thus, never reaching this point now. A past eternity or infinite regress of nature is self-contradictory, thus, false. That which is false eventually breaks down and is harmful to you in your life as an atheist which manifests in various ways.

Therefore, nature needs a cause outside of itself, outside of time and space, being uncreated. This uncreated Creator is whom we call God. Before going onto to deciding who the correct God is, first accept the uncreated Creator does in fact exist.
