Well Muhammad pbuh was illiterate.
Is the big bang a half baked idea ?
Do not the Unbelievers see that the heavehns and the earth were joined together (as one unit of creation), before we clove them asunder? We made from water every living thing. Will they not then believe? (Qur'an, 21:30)
Also the expanding of the universe was just plucked out of the air lol
And it is We Who have constructed the heaven with might, and verily, it is We Who are steadily expanding it. (Qur'an, 51:47)
The idea of clouds until recently is they are floating on air. Just recently it was found a cloud can hold up 300,000 tons of water. How they can remain aloft is truly amazing.
It is He Who sends out the winds, bringing advance news of His mercy, so that when they have lifted up the heavy clouds, We dispatch them to a dead land and send down water to it, by means of which We bring forth all kinds of fruit... (Qur'an, 7:57)
Christians have spent millions on Arabic scholars trying to find contradictions in the Quran. After all that time and money they came up with some lame findings.
A Quranic institute in Hanover spent decades collecting Qurans from all over the world, including the white house. They compared it to the first one and besides some typo mistakes the Qurans were identicals. This Quranic institute unfortunately was bombed by the allies in World War 2.
In the end if your heart is closed to the truth, no matter how obvious the signs are, you will refuse to see it. Some of you may still have time.
