Yes, I agree with you that a Greek guy did calculate the circumference of earth accurately , but still the general prescription at that time was that the Earth was flat----and there were many other rumors about the shape of Earth at that time , thats why i used theory of probability , to see how much a person could guess correctly
It wasn't just "a Greek guy" who knew the world was round. It was an established fact amongst educated people generally.
And it wasn't only "a Greek guy" who was busy making estimates of the Earth's circumference.
Marinus of Tyre also came up with his own estimate of the circumference of the Earth, which
Ptolemy incorporated into his own works.
That's Ptolemy as in the "Ptolemaic model"... IOW the most published astronomer of the ancient world, whose
writings were considered part of the "standard" education of anyone who actually received a formal education. One of the most well-known scientific texts of the ancient world explicitly declared that the Earth was round centuries before Muhammad was even born.
And it's not that this knowledge was restricted to Western society. The Arabic world had full knowledge of this. In fact,
Al-Farghani (a.k.a. " Alfraganus") commented directly on Marinus' estimates of the Earth's circumference not too long after the time of Muhammad.
It was common knowledge in the time of Muhammad that the Earth was round. While you might've been able to find uneducated people who didn't realize this, anyone educated to the point that they were literate (such as whoever wrote down the Quran) would've known full well that the Earth wasn't flat.
also the reasons why I believe that Quran didn't copied from Greek astronomer is due to these reasons
1) According to Greek Astronomer Earth was Circular while the actual shape of earth was Geo Spherical -----For all I know the Greek Astronomer might had thought that the Earth was Circular Disk in 2D like a 'coin'
No. And if you had bothered to find out
how Eratosthenes did his measurement, you would've known this. He measured the curvature between Alexandria and a town 500 miles to the south.
2)Quran is more accurate because our Earth is Geo Spherical like a 'Ostrich Egg' in 3D
No. Again: an ostrich egg is a prolate spheroid... a tall, pointy sphere-like shape. The Earth is an oblate spheroid... a short, fat sphere-like shape.
Is tall the same thing as short?
If we're describing a short man, whose description is more accurate: the person who says he's average height, or the person who says he's tall?
4) According to
Earth - Wikipedia, the free encyclopedia The shape of the Earth is very close to that of an oblate spheroid' but its not exactly 'oblate spheroid'----also the fact All eggs vary in shapes, roundness and sizes!
And
none of them are oblate spheroids. Eggs are all prolate spheroids.
Also the shape of earth is also changing so to imply that Shape of Earth should be exactly like Ostrich egg wouldn't be correct either
So you're saying that when the Quran says the Earth is like an ostrich egg, it's
not exactly correct?
