Is it a coincidence that there has been many sightings of this so called Bigfoot all around the world, and that there are folklore that go with each area. There has been many sightings recently but they have all been hoaxes, people dressing up as a big hairy beast trying to scare locals away or just for a little fun. This has been a conspiracy theory that has been kept alive through viral youtube theories. But the question still remains how did this start up? How did the fear of a humanoid beast prowling the forests start up?
What has stared up popular belief is that Bigfoot is himself an extraterrestrial. The possibility than an extinct breed of homosapians have survived in the wilderness with no contact with humans is obscured. A possible solution to how they could have survived these past decades is that they come and go as they please, they are an alien race that arrived at the time of our ancestors and helped them evolve. As we evolved they began to watch us in the shadows and observe our behaviors. The reason as to why we haven't seen any real proof of them on Earth is because they are not on Earth and are constantly coming and going, watching our progression. Some believe that they will appear when the time is right to guide us in the right direction.
