When you want evidence for God, many Christians will go right to Jesus’ miracles. Lets forget about hearsay, exaggeration, artistic license, rhetoric, propaganda, or indoctrination. Okay. Now that we’ve forgotten all that, we can pretend Jesus’ miracles really happened. Are they good evidence for God? No. There’s no logical connection between creating a universe and doing impressive acts of magic.
Appealing to omnipotence is a circular argument (miracle claims and omnipotence claims both come from the bible) and appealing to the supernatural isn’t a good connection unless God is the only supernatural being you believe exists.
