Aliens are Dinosaurs - Humans are Slaves - Bigfoot is an Experiment

Aliens are not from another world, they are from Earth, long before people were created by them to mine minerals for their vast cities under the oceans. Many Dinosaurs died off, some evolved into birds, while yet others oise to become 65 million years more advanced than us. Now they fly around in saucers.

They are constantly experimenting on humanoid forms and is the reason why no bigfoot carcass will ever be found.
