For an image to undoubtably be Him, He'd have to sew it in the fabric of this earth, as sewn as having a sun.

That with each sun rise, came rainbows that formed a 4K 240fps image of Him in the sky.

And with the words "Hi, this is an image of me, God" at it, of a kind of stone you can't even get on the earth. That you could fly up to it, and see they are not from the earth. But they are noclipped. You can pass through them.

This is speaking of other than Him walking on the earth as man :)
