Hey brotha Omo,
I think the idea of a Sothis calendar is worth looking into. Perhaps we might find that some significant Sirian event took place in the first year and our attention has been drawn away from it by the fable of Jesus.
I must admit I did not read to the end of this article because of the author's insistence on trying to shoehorn Egyptian history into the Bible and his seemingly obfuscatious mathematical formulas. Interestingly enough the biblical date for the birth of Adam (excuse me, I thought the cat was created not born) and creation of the Earth coincides with the Masonic Age of Light.
Brotha, if I missed something because of my impatience with the author's theology please let me know and I will bite my lip and go back to read the rest of it.
