Nephilim, Stargates, and The Devil's Graveyard

I watched 'The Devil's Graveyard" documentary on the History channel yesterday. It wasn't this particular film, only part of it. It was a story about a scientist who's son died in Algeria when their family dog went mad, likely due to the magnetic field affecting that area. He has spent his whole life investigating these 12 areas of the world (12 ) triangles, including the Bermuda's triangle, as well as the reason for that missing airplane that went down a few years ago.. disappeared completely. As a simple homemaker, I am not very informed about these things, but science is fascinating, and I have great empathy for the scientist who  who lost his son.
