actually, i don't get your confusion :\
he's saying that god, instead of writing down jesus words, had jesus followers write it down from memory 12 yeas* after jesus death. then he implies that it would be unreasonable for us to expect that said god would write down the bible in modern English for modern people to understand.
he then mentions the coran**ironically implying that this one is even better than the bible, saying that this one was written by people who didn't witnessed what they were described, written in stones or pieces of wood, and later compiled by people who had their own interests in mind instead of "god's"***
then he mentions the torah, saying that this one is a recollection of old folk tales, and he ironically advises us to take it literally, instead of accepting that the secret of the universe wasn't revealed to us by an almighty god, and instead of exploring the universe through science, we should wait for god to tell it to us
*i've read that the bible wasn't written anywhere near christ's death, tough, nor by any of his disciples, it was over a 100 years after christ's death. wikipedia:All of the works which would eventually be incorporated into the New Testament would seem to have been written no later than the mid-second century.
**(Coran is an infrequently used English spelling of Qur'an)
***it's the bible's story also, not just the quran's
