Its interesting the way the connection is made in the video.
I believe it was the third generation college kid of the proprietors of the land, that was playing around on google maps and knowing that the design was a summer solstice representation, he linked that precise line of site and it carried through to the location of the Stonehenge in England. So he played around with the directional lines correlated at various lines as prescribed by the layouts, and it linked with precision the tip of the pyramids. As well the same results linking to other locations of interest including Jerusalem.
