I have told you many times, I would accept any proof you can provide.
A selfie with God and a card that says: "BADecker" would do.
A post from God in this thread would be acceptable as well (please include my ATM card PIN number)
God is the one who produces proof. The universe is the proof of His existence. If you won't believe the universe proof, you wouldn't believe a selfie or ATM card and PIN.
