Bigfoot: Physical or Spiritual Creature‪?‬

I have long been fascinated with Bigfoot and I am a believer.   Is Bigfoot a Physical Creature or a Spiritual, inter-dimensional being? Is Bigfoot going in and out of portals or being sent by UFOs or simply a type of ancient human?  We explore those theories, along with ideas of what Bigfoot is made of and a few case studies.   I also take a look at the DNA question and evidence.
