That's utterly meaningless, feargod.
Even if Muhammad was illiterate, doesn't mean he was stupid.
Christian missionaries often to the populace, who were generally illiterates. And there were Jews living in Arabia, and Christian missionaries coming and going everywhere, including Arabia, and there were trades going between the Arabian tribes and the Byzantine Syria, so pre-Islamic Arabia.
There are other ways to learn other religions, that doesn't involve reading and writing - learning through listening.
People, in illiterate societies, where bards used to teach their apprentices through passing down stories or songs, just by listening and remembering, known as oral tradition.
And don't forget ancient Jews (Israelites and Judeans) have been passing stories and exegesis of the Oral Torah, generation after generation, supposedly since Moses' time,before they were written down in the Talmud, Midrash, and other rabbinic literature.
And if I remember correctly, while he was with his uncle, have encountered a Christian preacher, so clearly he wasn't ignorant to biblical stories.
Muslims' claims that Muhammad was illiterate, is a pointless claim.
Illiterate doesn't mean ignorance or stupidity.
