History

Many believe that bigfoot is a newly added addition to mythology, The word bigfoot was thought up in 1958. But the the story has been around much longer than that and is also not limited to just North America. The earliest accounts of the creatures appeared 4000 years ago on 12 clay tablets known as the epic of gilgamesh. Cretaing a story between Gilgamesh and a "wildman". 
     In the new world the natives refered to big foot as "tai-he" or more commonly "Sasquatch",  which means hairy giant. Big foot experts and enthusiast estimate that their were some where between 4000-6000 big foots that roamed North America at one time. Big foots are known to be docile and vegetarians. But there has also been reports of big foots working together to capture and kill deer for their livers, which is a high protein source. 
    Big foot was first reported to be seen by a white man in Jasper, Alberta, Canada in 181. Since then hoaxes have been all around referencing the canadian Sasquatch sightings. The first reported attack was in Washington State where miners reported a big foot throwing rocks at their cabins and big footprints as evidence. Most of the big foot craze subsided until the 1950's in California. A plaster footprint of big foot emerged in 1958, founded by Jerry crew. He found the print while operating a bulldozer. This is where the common term Bigfoot came from. 
    The biggest craze came from a small clip that only contained a few seconds of what appeared to be a female Bigfoot, walking away looking at the camera. This is the most famous of big foot videos and is known all over their world.
