There is a section in the Quran that tells you if any part of the Quran contradicts itself use the later portion.

Show me this "section".

If one has in his mind that he would like to know how biological processes work in a specific manner so that he can create modern medicine, he will avoid the vague Quran.

You are speaking of looking through the Quran for the creation of modern medicine, through a biological process, in a specific manner. If the Quran were to list every possible way of surgery and medicine and healing, as well as every minute detail of every single aspect of our lives, it would be an encyclopedia and not a Holy Book stating not how to do every little thing in our lives, but the morals and laws we should live by.

You are using books that are supposed to help you be a better person, not to deliver the truth. You are using it wrong.

Firstly, who are you to tell me how to use books, let alone Holy ones?

Second, why can't being a better person be part of truth? Are you saying that being a better person is only related to "fiction", and that rational people are not good people, and don't strive to be better?

I completely understand, and find your viewpoint completely respectable. Had I been in your position, I would have undoubtedly had the same opinion. I mean to tell you that I am a human of rationality.

However, having looked into the Quran, I found that there are no contradictions, no vile thoughts or views. Not only that, but I found that it contained scientific breakthroughs that had only been discovered recently, while the Book had been written 1400 years back.

People may complain that the scientific knowledge in the Book are too "vague", but if one has it in his mind to disbelieve, he will.

One must look upon the Books (Bible, Torah, Quran) in search of truth, not anything else.

Why would you suppose that we were "quick to say that God exists without a doubt"? You do not know what went through our minds, sir.

You do not know about the journey we have been on to reach this point, sir.

So, please, try and think of the other as a person who thinks before you assume.

And keep in mind that your assuming is supposing something is the case without proof, without thinking.

The thing about God is that we cannot find any proof that he is not there.

And if one has it in their heads that they will not ever even try to believe or understand, they will not, even if they have all the proof they need around them.

In truth, there is only one God. There is no "Christian God" nor "Muslim God" nor any other specific religion-related God. If there is a God, he is one.

One cannot possibly look at the universe around them and claim that it was a mere coincidence, or that nobody created this beautiful system.
