Well apparently I was wrong. The Qur'an logically must be correct, and therefore god must exist:
The Qur’an speaks about hundreds of things that were not known to men at the time of its revelation. Only in three options the result is .0017%. I leave it upto you, to work out the probability if all the hundreds of the unknown facts were guesses, the chances of all of them being correct guesses simultaneously and there being not a single wrong guess. It is beyond human capacity to make all correct guesses without a single mistake, which itself is sufficient to prove to a logical person that the origin of the Qur’an is Divine.
The 3 options mentioned are the Qur'an saying the world in round (known by the ancient greeks, and any sailor who's seen a ship sail over the horizon since the dawn of time), the fact that the moon gives off reflected light (given that you can see the features on it and not the sun or other stars, not too unreasonable), and the most unlikely correct statement, that all life is made of water.
It's difficult for me to point out how obvious it is that life on Earth is based on water. We drink it, we see animals drink it, we bleed liquid, we sweat it, animal meat is moist, corpses look different after they've had a chance to dry out...you'd really have to be a moron not to figure out that water is important.
The main logical error being committed here is assuming that prior to roughly 1700 A.D., people were complete idiots. Eratosthenes figured out the size of the Earth, in fact. The sad fact is that knowledge can be lost after being gained, and just because group of people knows something about the natural world, doesn't mean all of humanity knows it. This is still true, but was more true before books, newspapers, postal services, telephones, and the internet.
The other error is assuming that you need to be able to build an electronic computer, put a camera in a satellite, and snap a photo to figure out the shape of the Earth. You don't. See a ship sail away? The fact that it disappears from the bottom up (instead of to a point) means the Earth couldn't be flat. You can also observe the shadow the Earth casts on the moon during an eclipse. It's always a circle, something only possible if the Earth is a sphere.
Then there is the logical leap that, even given the Qur'an unlikely getting things correct, it must've been written by the creator. It could've easily been written by a more advanced Earthly civilization, or aliens. Or, even if it was written by a god-like entity, that's not proof that praying 5 times a day and stoning adulterers is correct or necessary.
Error rating: 6. Each logical error is slightly understandable, but there are several.
