There is no such thing as Bigfoot and I have the evidence, or lack thereof, to prove it.
An Idaho driver recently said a Bigfoot sighting caused her to crash her car. The woman told a local sheriff's office she saw a Sasquatch chasing a deer on a stretch of U.S. 95 outside of the town of Potlach in northwest Idaho. She described it as "shaggy," tall at between 7 and 8 feet. As the unidentified woman was checking her review mirror, she slammed into a deer. Checking out the story, officers went to the scene and reported no evidence of a Sasquatch.
This woman did not see a Sasquatch. I don't know what she saw, but I can guarantee it was not Bigfoot. I'm not a scientist and have no field experience in the search for the legendary hairy giant man-like creature. However, I have a bit of evidence, or lack thereof, that can not be refuted. Where is Bigfoot's poop? Seriously, a creature that big must produce a significant amount of waste. Ever cleaned up for a Great Dane? All I see are pictures or castings of big deep footprint impressions. Isn't it reasonable to assume the person who discovered these tracks would have stepped in it?
If the poop question is too much for you, I've got a more serious one. Does your dog shed? Isn't it safe to assume that a hairy seven foot tall creature that walks upright would leave behind some dander? Where is the follicle that when tested would show a DNA never before seen in the animal kingdom. Finally, forget about the fact that no one has ever produced a dead Sasquatch, not even a single bone. They certainly can't live forever.
The bottom line is that Sasquatch, the Yeti, and any of their cousins are just a bunch of BS.
