Our eyes follow lines to their natural conclusion. A boy pointing in a photo, you’ll first follow their arm and hand to where they are pointing.
What’s happening is you as the viewer are following those lines as the first thing you see and then trying to visually parse the various craft that the lines point to.
Hence why for many of us the ufo takes further effort to find, as it is has deliberately been placed outside of the dominant focus area.
Either that or whatever latent racial issues might be in Canada would touch off and turn the place into nothing like we’ve seen up there before.
