Already provided it. A black sun means no light which means the moon is black also therefore it is the color of black blood.
Rev 6:12 And I beheld when he had opened the sixth seal, and, lo, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood;
Now, you try to prove it will be a red moon while the sun is black. I'll be waiting lol
The proof that the sun will be black, and the moon will be as blood is the Word of God.
The difference is, I believe in the written Word of God. You believe in what you think is possible.
God says the sun will become black as sackcloth of hair and the moon will become as blood. I believe what God says, but you can't believe God because it won't fit in your end times timeline that you have concocted. So instead of believing God and figuring out how that timeline works, you claim what God says is impossible, a walk along in blindness.
You say, God can't be correct because it is impossible for the sun to be black and the moon to be as blood.
Luke 1
37 For with God nothing shall be impossible.
You believe what you can see with your eyes. I believe God. That's all the proof that's needed. God said it. I believe it.
Now about that huge problem with the stars that fall from heaven at the 6th seal, which you keep avoiding.........................
