Some scientists believe there are small wormholes right here on Earth. A wormhole is a basic shortcut through space-time. If there were wormholes on Earth they would probably be in places like the Bermuda triangle, or Lake Chapala, Mexico. What I am getting at here is that maybe the thousands and thousands of cases of people encountering extraterrestrials in some way are interacting with being that don't come from (or travel through) space, but come from right here on Earth. If aliens are centuries more technologically advanced than us they may be able to find some way to travel through and manipulate wormholes, maybe even create wormholes. This would explain the countless sightings of UFO's coming out of the water at Lake Chapala, Mexico and the lack of radio and satilliete frequencies functioning properly around the lake, as well as the dissapearances and UFO sightings in the Bermuda Triangle. We may be too busy looking at the stars for aliens when they are right in our own backyard. Just my theory. What do you think?
