The universe cannot come from non-existence because the latter does not exist. That which does not exist can't cause anything. Nor can nature always have existed, because if it had, you would by that definition have happened already, having had an eternity to do so. Therefore, nature needs a cause outside of itself, outside of time and space, being uncreated. This uncreated Creator is whom we call God. Which God? The Trinity since nobody can find a naturalistic explanation to account for the eyewitness testimony of the Apostles in various group settings seeing Jesus alive from the dead. Consequently, by not receiving what Jesus did on the cross for you and the sins of the whole world, you are going to Hell. Essentially you are saying you want to be eternally separated from God of the Bible and the love of God. This evidence is loud and clear so you are without excuse (Rom. 1.20).
