Yo why you keep ignoring the main question in the post? Who wrote it?
Sorry, just saw it.
You're asking a philosophical question, so we can't answer it like typical Somali FOBS do, it needs a philosophical answer. We have to break out David Hume on it. It's a bit long, but bear with me.
Okay here's the deal. The Quran is the words of Allah, but it's not the only words Allah has spoken. He's spoken plenty since these 1400 years. He talks everyday, to his angels, to people in jannah, and probably to extra terrestrials. Only an unscientific moron thinks we are the only intelligent life in the cosmos. The words he spoke to Bronze Age illiterates a millenium ago who thought the earth was flat and had never heard of black holes and dark matter are simplified instructions for a simple people. To more advanced civilizations, he would address them differently.
The Quran is what backward Arab tribes could handle. It is by no means the last word of God. There is no last word. He is talking every day. He's got opinions on modern issues like climate change, nuclear weapons, GMOs, space travel, Artificial Intelligence, and IVF which are not covered by the Quran. These are life and death issues, they're not trivial. So God certainly has strong opinions about them, and he knew they would be important issues when he revealed the Quran, yet he chose to leave it out. There's a reason for that. The Wahabbis think it is because Allah forgot, or did not know about them at the time. That's not what they say, but that's the implication of their argument.
The reason God left out this stuff was because he wanted us to use our brain to work it out for ourselves because the most sacred object in the world is the brain. That is Allah's greatest accomplishment, its the most complex thing in the known universe. Thinking is a sacred act. Allah is a thinker, a philosopher, a scientist and a mathematician. And he likes fellow thinkers. The thinking, enquiring, discovering human mind is greater than the Kaabah. It's just a building made from bricks and mortar. But an Isaac Newton is really a miracle.
Who made the Quran? Allah. But he also made the Andromeda galaxy. Both are his signs. People who focus only on the book are missing the big picture. Science is as essential to understanding Allah and his creation as the book. An Islam without science leads only to ignorance, poverty, disease, and barbarism. Pretty much what you get in the Muslim world. That's why Einstein knew more about Allah's universe than low IQ ragheads who chant his name but don't know a thing about how their own body works. They can't tell you how the liver functions, but they wanna comment on the heavens. God help us.
