Muhammad and illiteracy
Some Islamic apologists claim that Muhammad could not be the author of the Quran, because he was illiterate and it's somehow impossible to give made-up speeches if you're illiterate.
Is reading the only way to get information?
Humans have 5 senses for getting information from the outside world:
- Hearing (!!!)
- Sight
- Touch
- Taste
- Smell
Human can receive information by listening (hearing). Verbal communication is a common way to get information. This point is probably obvious to everyone, except Islamic apologists.
So Muhammad could get information without being able to read and he could give speeches which contain these information. And besides that, he could also be inspired by himself, by his wishes and he could use his imagination.
