Perhaps He didn’t do what you think though?
As you said, it’s a matter of faith. Especially since none of it can be proven, and since we both agree that God can do anything, maybe we’re both right, or wrong?
Overall, the most important thing is that you place your trust and faith in Jesus as your Savior.
Having done that, you read His Word. It says:
John 1:1 In the beginning was the Word, and the Word was with God, and the Word was God.
2The same was in the beginning with God.
The Word, is also the Bible.
Genesis is true, as written. God and Jesus being one, and the Word, I’ll beleive Them/Him rather than a mans theory.
