A far more simpler explanation is that Jews have been living in Mecca and Medina for generations, and Christians have been travelling and preaching in and out of the Arabian peninsula for centuries.
The people of Mecca and Medina weren't cities living in isolation, so many of the better known biblical stories were known to them.
And the people didn't need to read to know the stories, because Christian missionaries often preach before listeners.
Not everyone could read and write.
To say that Muhammad didn't know stories of Adam, Abraham, David and Jesus, is a bit naive or ignorant.
And your "unbiased" sources that Jews lived in Mecca in time of Muhammad; and their population there.
