Yes, indeed. There are many faiths with great any scriptures and versions which have been changed by religious leaders etc. Except for one, the Qur'an. I can guarantee you that the Qur'an have never been changed, not a single verse have been added or removed by anyone and there is only one version since the time of revelation over 1,400 years.
And we still have the original copy in Turkey, and it is exactly as the text today as it was when originally revealed.
Time does not permit me to go into great detail into the sciences of the Qur'an and Hadith (tradition and says of Prophet Muhammad (Saw). But, you're more than welcome to look into it yourself and you'll discover how they have preserved and authenticated unlike any other religious books or materials.
Apologies for the long explanation, I'm not here to convince you otherwise but, to share information and why Muslims believe in God and that He does exist. It is based on evidence and not chance.
If you believe in science I can give you information from the Qur'an that will make you wonder how can these information be in there.
But, again, believing in God must be with sincerity when one certain God exists and just have blind faith like some religion insist on.
Islam is all about facts and recognising the signs of God in everything he has created out of nothing and one's own self.
God tells us to look at yourself and see how you are created with perfection as God wants to.
Contrary to popular belief, one cannot be forced converted to Islam because it goes against God's command.
"There is no compulsion in religion, the right direction is clearly distinguished from the wrong."
Moreover, how can you force one's heart to believe in something against their will? You can compell something to utter something but cannot change their heart unless they freely want to.
Muslims believe in the old and new Testament being the God's word once in their original language but not the present text as they have been corrupted by people and changed the text completely. Although, there are still some original bits left in it but, that's only because it matches what is written in the Qur'an.
Anyway, I digress, sorry about that. It's difficult to discuss about something without explaining it properly.
