I conclude that Quran is not human made, because:
The writing style and composition is very distinctive and outperformed high ranked poem made by Arabs, that no poems or any literature in Arabic can equal it until present.

This is a matter of taste.  I prefer any number of childrens nursery rhymes to anything in the quran.  All you could be saying here is you think it's really..really great - but people do write really great stufff.  Like...alot.... FWIW, as a claim...it shits on the entirety of arabic literature while it's at it. I'm not an expert, maybe it is all as bad as you claim.

The texts itself compose of prophecies that are true. Rationally, human can not do prophecies.
The texts itself contains science facts that impossible people from that era to know.

Good luck with quranic miracles by any name.  This is magic book territory. Do you worship a god, do you have beliefs about right and wrong and how the world ought to be vis a vis the divine and taboo.... or do you worship a magic book and have novel ideas about printing? This where I'd place the line between superstition and religion.

If you were to discover that people did, in fact, write the quran...would you stop believing in gods or your god? Would you reject the religion of islam?
