Did I?

To answer that, no, I didn't. But after seeing this, i did a 5-second google survey and found articles stating this study " debunked" and "proved." The article linked here uses the word "shown," and you have to get 4 paragraphs in before words like "proposed" get used.

So while i didn't make that jump other people did

And to be clear, I dont support the author they are going after in any way. The notion that northwest europeans in Britian communicated enough with Eastern Mediterranean cultures (Egyptians) to obtain, understand, and utilize their calendar system in 2500 bce is sort of silly.
