1. Big Bang
2. Scientific Miracles in The Qur'an
Miracle One:
Miracle Two:
Miracle Three:
Miracle Four:
Miracle Five:
The big bang has nothing to do with meshing or the "earth" or the heavens. The author of that verse obviously thinks the earth was among the first products of the big bang, which is not true. The earth and heavens "meshing" has zero to do with the big bang and our understanding of it.
It says everything is made of water. Absolutely not true. It doesn't say the human body is 70% water. It also forgets to mention that not all living things are mostly water. For example a whale is 40% blubber, which is not water. You are stretching a bit if you took that verse to mean humans are mainly water.
At NO point does semen become a "clump" and then a "clot of blood". This simply never happens. If you try to fit this with a modern understanding of science, you're obviously stretching. It reflects people's thinking at the time and nothing else. It was closer to scientific views of the matter than cave people but still obviously way off.
As for the burning in hell verse, it just says you'll be burned and as you die out, everything will be restored so you can keep keep feeling the pain. Again, it doesn't take scientific knowledge to conclude that if you burn someone alive and bring that back to life to burn them again, they'll feel the pain all over again. Note, there is nothing scientific about bringing people back alive. Also note how barbaric and pathetic it is for the so-called creator of the universe to use threats of torture to keep you from leaving his cult. Almost as if he feeds on praise, sort of like Donald Trump.
And as for rain, you do realize the "bright flash" refers to lightning right? Lightning certainly doesn't come from mountains of ice in "the heavens". Clouds rub on each other, become charged and build a high voltage and electricity ionizes air molecules and travels through air from an area of high electrical pressure to an area of low electrical pressure, hence lightning. Again, this has absolutely nothing to do with mountains in heaven or whatever nonsense that verse spouts. Did you write the commentary? Because you are stretching wildly and trying to make sense of it. It doesn't make sense and you should recognize that and leave it for science.
