Dear stupid: how many times does the earth rotate in a year?

[GUBU]

Good answer my friend. But since the Ancient Greeks that u refer to with this scientific knowledge, didn't come into existence until after Islam (the 7th century), The knowledge had to exist with some higher being before. God Himself

I think you have a sign error in your calculation. All the ground-breaking Greek stuff was in years BC, Islam was created AD. Eratosthenes had already measured the circumference of earth when all things Islam weren't going to be around for nearly another thousand years

How can you know so little and yet speak with so much confidence?

Because he knows so little.
