Can anyone please refute these verses of Quran (or at least their interpretations)?

I'm sure the Hindus are adamant that their texts have been the same since the start - after all they have the Vedic Chants, which mean even if all of the Vedas were destroyed people would still have access to perfectly memorized Vedas.. When you say "constant forgery" is just conjecture. The burden of proof is on you to prove that. Sure, Hindus kiss black stones too, and Christians are always trying to say Muhammad held Pagan beliefs, just as Hindus say Muhammad copied from them.

I just recently found out that there is/was a branch of Ismā'īlī Shīʻa that believes there were only seven Imans (rather than the twelve modern twelvers who are part of Jafari rather than Ismā'īlī), aptly named the Seveners. Don't think your religion is the exception. People are always disagreeing with things and they all have biases. Maybe they thought: Jesus had twelve disciples so why can't we have twelve Imams?

So what if the Quran hasn't changed? The works of Shakespeare haven't changed nor have the musings of Confucius. If people love something they will take good care of it. Yet somehow the Quran is special for not being changed even though loads of literature doesn't change.

There are a growing number of scholars that say Jesus didn't exist. Noah has been debunked already because his story is just so ridiculous and a rehashing of the Epic of Gilgamesh.. That it is interesting. If people can say one prophet didn't exist then why believe the others.
