This is a documentary about the people leading the way in this movement and nothing to do with science. The couple bits of science they did try to throw in were miserable failures.
I worked at a monument in Lake Erie. I was there while it was scaffolded for restoration. Part of my job was to document the work, so I climbed down the 317 feet of scaffolding a number of times. On a clear day, the Sears Towers were visible far off in the distance from the top. They disappeared below a the horizon as I descended. That's sort of like the sailboat sailing off into the distance and disappearing, only in reverse. "But light gets bent in the atmosphere" is an argument I often hear to explain that away, yet one of their "experiments" they attempted to use to "prove" their position was using a laser set up dead level. Well, laser is ligjt. It would also get bent. Sorry, you can't use an argument to explain something away when it serves their agenda and then dismiss it when it doesn't. BTW, their lame experiment failed miserably at a tiny distance of only 3.88 miles. My observations of the Sears Towers was over a vastly greater distance.
Also, for point of reference on where I come from as far as science is concerned, I do not believe in Neo-Darwinian, macro evolution. The reason I do not is because I have an advanced education in genetics. Because of my education, I understand the shear statistical impossibly that advanced life just happened by accident. Do I have an explanation explaining it? Heck no, but then true knowledge is knowing how little we know.
