I will repeat for him:
Doesn't the sun rise in the east and set in the west in your world? You're too obsessed with the sun revolving around the earth concept.
You might spend a few moments calculating the effects of slowing the earth's rotation.
You might spend a few moments calculating the effects of falling into the hands of the Living God, who overrides nature.
If you are going to promote faith with threats I suggest you try Islam.
