You'd be surprised to find out how many atheists actually do believe something come from nothing in order to reject their Creator. That's why they allege in quantum mechanics things happen from nothing all the time. Not true of course. Atheists can't agree on anything. They keep changing their stories.

We do know the cause of the universe because of the combination of three facts which are beyond a reasonable doubt: 1) something can't come from nothing, 2) universe can't always have existed, 3) Jesus and the Apostles proved His resurrection. Since you have no naturalistic explanation for these well evidenced facts, realize God exists (that is, the uncreated Creator) and Jesus is God, salvation is through Him and there is no other name under heaven by which one can be saved. Unless you confess the Lord Jesus as your Savior before others, He said He will deny you before His Father in Heaven. Your choice.

Ergo, God created the universe out of Himself. All He does is perfect. He couldn't create a more perfect universe than this one. Realize you are going to Hell, because you want to be eternally separated from God. You have decided already, so now you want to understand why you are going to spend eternity in Hell for Jesus said you are "condemned already" (John 3.18). Who is a liar, you are or Jesus?
