Well, those who rely on the quranic science are the same sort who would rely on the bible code to claim the future can be predicted. It is people trying to find something to validate their beliefs when simply believing for their own personal reasons isn't enough - it as though they need validation from peers, both inside and outside the faith as confirmation that they have the absolute truth.
It is quite pathetic really to watch.
Muslims tend to have a slightly different criteria for claiming that Islam is the truth.
1 - Mo couldn't read or write and could no way have obtained that information. To suggest that he did is merely conjecture and there is no evidence to back it up.
2 - The Quran is preserved and it's preservation can be traced back to the Uthmani Quran as well as the many Quran Hafiz throughout the world.
3 - Allah has guaranteed it's preservation in the Quran itself.
4 - The hadith are eye witness accounts (traced back through isnaad) of his life and deeds, which verify his "miracles". His contemporaries knew him to be trustworthy and honest which backs up his claim to Prophethood.
Now, this is the type of response that the muslim will give. There are flaws with all the arguments and at least one of them is circular. I'll let you spot the flaws while I check out the other threads.
