LOL, Scripture clearly teaches a definitive beginning to the universe as we understand it. Try Gen 1:1.
If somebody who doesn't believe in God can't grasp Gen 1:1 after 16 years of immersion in that type of environment, he/she provides a marvelous testimony of how the Word of God is not without effect. To those who reject Him, their hearts are simply hardened.
Not to worry though, every person alive still has opportunity to return to Him prior to the first death and be blessed with eternal life and many ther blessings by Him resulting from just a smidgeon more faith than absolutely no simple faith alone through Christ alone.
Okay, I’ll note for the record that creationists have always advocated the Big Bang theory and that they somehow convinced scientists a few thousand years later of the fact.
Any thoughts as to what God was doing for infinity prior to creating the universe?
