Gotta say the genesis account never says the fruit was an apple. That idea was depicted by artists who usually drew the tree as an apple tree.
And the Devil was not first called Lucifer until the third century.
And Mary Magdalene was not first conflated with the sinner who washed Jesus' feet until the sixth century.
An awful lot of what we take for gospel (if you'll excuse the pun) is either artistic license, later theological addition, or just confusion so old it's become ingrained.
...It's also important to remember that there were a number of other books that were not made part of the "official" bible in the 4th century, some of them for largely political reasons.
