Do you know WikiIslam ?

[R00tKiT]

Yeah, you can just see it, he personal interacted with hundreds of thousands taking the time to convince them all.  

Why would he need to personally interact with everybody? I can be convinced of Martin Luther King's speeches without ever seeing him.. I just need his speeches.

The science of the hadiths, again with that nonsense.  

Yeah it's pretty important for Muslims, y'know. Without hadiths, there is no way to know how to perform the most basic religious rituals, starting with prayer.

It's actually more important than that, it's not clear what being a Muslim means in practice if we exclude the hadiths. The so-called 5 pillars of Islam are only found in an authentic hadith. 

This explains how some people can end up thinking that hell is black hole.. when reading verses of the Qur'an in isolation, without being equipped at all to interpret it correctly.

Do you think that god split the moon in two, and that a game of telephone can gaurantee that premise as a fact

Not really. If a person believes that:

(1) God exists and intervenes in the world.
(2) The Qur'an is the word of God and inerrant.

Then it follows that one believes that God split the moon, as this miracle is actually mentioned in the Qur'an, an entire chapter of it is called al-Qamar (moon in Arabic).

The Hour has drawn near and the moon was split ˹in two˺. (54:1)

In short, we believe in this miracle because we believe some premises about the Qur'an being of divine source and inerrant etc etc. Not directly because of the chain of narrators.

There are however other reported miracles that aren't found in the Qur'an, like the prophet feeding a small amount of food to almost 300 people, this is an authentic hadith as far as I can remember, it's similar to the "feeding of the multitude" miracle in the Gospels.
