Sir82 said, "It was Freddy's idea all the way. He thought it up all on his own and pushed for its acceptance."
Well, not entirely, really. First it seems that "Perfesser" Franz accepted the basic premise of Archbishop James Usher's (Irish Protestant) decision in 1654 to "reverse-engineer" his Bible so that he could determine the "Bible-based" date for the creation of Adam. Usher settled on "the entrance of the night preceding the 23rd day of October... the year before Christ 4004"
Our Beloved Perfesser Freddy (Peace be upon him) had confidence that he could repeat Usher's exercise, which he did, several times, each time 'discovering' a reason why God's revelation to him was incomplete and innaccurate. Two examples are the 'discovery' that there was no year ZERO, and that Eve, God's presumed last creative act, was not created immediately after Adam, but some unknown period of time later.

Then there are the undocumented contributions of Freddy's Jewish-Iraqi Bethelite friend, Natheer Salih. In fact, Mssr. Salih is so underdocumented as to be invisible, so I am going to do a very cruel thing: I will drop his name and then drop the mic.
