21:33 - “It is He Who created the Night and the Day, and the sun and the moon: all swim along, each in its orbit.”
What's the doubt?
Your honesty is the doubt.
I believe the quote is actually, ""It is He Who created the night and the day, and the sun and the moon. They swim along, each in
an orbit."
Each in AN orbit. Given that the moon and the sun are both being cited, in the same sentence, as being in an orbit, which is more likely, that the author believes both to be orbiting the Earth, or that the moon orbits the Earth but the Sun orbits a point within our Galaxy?
Which is more likely? If you want to cite your 'holy' book as being a miraculous source of knowledge centuries before its time, then you can only cite the text within it, not simply choose to infer from vague ramblings the basis for advanced scientific knowledge.
As has been said, Muslims have contributed to mankind's knowledge throughout history, but that knowledge was not because they were Muslim, it was because they applied scientific and mathematical principals which could be objectively supported and proven, you know, exactly what 'Science' is.
