A better title for the article might be:
Why IS Orkney the Center of Neolithic Britain?
It looks to me like these folk just kept traveling until they came to the outermost edge of the end of nowhere—and then settled down by that peaty ness to grow some grain and think about why they were there.
Somebody dropped some grain in that peaty water and and thus they invented usquebaugh, the Water of Life.
Then somebody said,”This stuff is so good it must be from the gods. Let us build a temple to celebrate the “Water of Life” where we can get out of this miserable weather.”
And so for millenniums, the Orkneyians lived there, drunk and happy.
And there, my friends, is the real story about this archeological find.
