Why is the Quran vague?

Why is the Quran Vague?

"Imagine the Quran was a strong miracle that was 100% compelling and there was no vagueness in it and it was direct---We'd all believe in God and life is no longer a test. (everyone saw the undeniable proof. it simply doesn't make sense for the quran to not have a level of vagueness)"

If you wonder why verses in the Quran are vague and don't 100% show God, consider these points

Point 1: God created humans to test if we worship him without proof of his existence
Point 2: If God created humans to worship him without proof of his existence, then he has to give us sufficient evidence.
Point 3: If God has to give us sufficient evidence, it cannot be a strong enough evidence that automatically 'proves' God. The evidence has to be there, but it cannot be too strong.
Point 4: Therefore, God gave sufficient evidence for those whose hearts are open, unbiased to show his existence, but that evidence is sufficiently vague so it doesn't compel those whose hearts are closed.

Imagine the Quran was a strong miracle that was 100% compelling and there was no vagueness in it and it was direct. Imagine the Quran listed scientific phenomena so clearly that in the future everyone knows its divine. Does that make sense for God to do that given the fact that our purpose in life is to worship him without 100% proof? If he gave us really strong proof of his existence, then our purpose in life is violated. We all believe in God and life is no longer a test--because everyone saw the undeniable proof.

Life is like multiple choice exam. If you pick the wrong choices throughout the test, you will be punished; if you pick the right choices throughout the test, you will be rewarded. The exam is going to have many tricks in it to test you. This is like life. Make the right choices. If the Quran was presented with clear 100% proof of God, then everyone believes in the Quran and God. Its like the professor decides to give everyone the answers to the exam--Whats the point of the exam?

The Quran must support ancient beliefs AND reality (scientific facts):

Point 1: If God were to give a revelation to 7th century nomads it has to compel them and has to give them things to reflect upon so they believe in the scripture
Point 2: If that revelation is the final revelation and is supposed to compel people of the future, then that revelation cannot contradict reality that future humans will discover
Point 3: Therefore, the Quran MUST affirm 7th century belief without contradicting science.

And it must be sufficiently vague (read my past logic)

So yes, you find that in the Quran many words are purposely avoided or the Quran used alternate words so it could affirm 7th century beleif without contradicting (but supporting) science. So the Quranic scientific miracles have to be vague enough so they don't compel those whose hearts are closed and has to (at the same time) NOT contradict 7th century belief.

Imagine Muhammad directly told everyone at the time that the Earth is round and that you are standing off of the middle and God has made it so you don't fall off. Image Muhammad told people directly that mankind's parents were primates. People at that time would have considered him "idiotic" and "unscientific" and would have never considered Islam. So what did God do? In the Quran, there isn't a single verse that says the Earth is flat and there are many verses that hint at the Earth being round and there are many verses that hint at evolution. Those have to be sufficiently vague enough so it doesn't compel those whose hearts are closed AND not contradict 7th century belief AND support modern science.

So why does the Quran sound so basic and why didn't the Quran cover extensively the complex scientific topics?

God patronizes us in the Quran. He knows we are only limited to understanding certain things, and that is what he utilizes. So of course the Quran has to give 7th century people something to reflect upon. Its like me trying to explain the theory of relativity to a 2 year old. I am going to sound like I am 2 year old and I am going to avoid using bigger words and complex topics. Right?

Life is like multiple choice exam. If you pick the wrong choices throughout the test, you will be punished; if you pick the right choices throughout the test, you will be rewarded. The exam is going to have many tricks in it to test you. This is like life. Make the right choices. If the Quran was presented with clear 100% proof of God, then everyone believes in the Quran and God. It's like the professor decides to give everyone the answers to the exam--What's the point of the exam? It's not even an exam anymore.

If someone puts a gun to your head and tells you "say you love me, or I'll kill you" and you say "I love you", those words are not meaningful. They're only meaningful when you have a perceived opportunity to reject that relationship with God. There is an area in the world where either condition can seem plausible to you (believe in God or reject God). If there was no inclination to disbelieve (or do what is wrong), then wicked people with a heart made of stone would be compelled to believe in God. There has to be enough information in the world where those who are loyal or have an open heart to God can see the truth and pursue a relationship with God, but there has to be sufficient ambiguity in the world that enables those with a heart of stone to reject God--perfect balance.
