Ok, I'll entertain you
A snake doesn't have the ability to talk in human language. Nor is there any talking creature with the ability to shapeshift into a snake.
There's no proof for a global flood of the magnitude of what is Noah's story. There's no type of remains or evidence of something that should've left millions of human and animal victims. And there's no timestamp to when it happened nor does it explain the diversity in humans or animals that's present in a post-flood world.
My time to play
According to islamic lore, the Buraq (which is a horse-like creature) transported Muhammad from Mecca to Jerusalem and back in a single journey. Do you believe in this story? If not, prove to me that the Buraq doesn't exist or that travel never took place
Do you believe in Jötunns? (
Jötunn - Wikipedia)
If not disprove them to me
