Why is bigfoot a mystery?
because novody knows if heis real.Go on youtube and watch bigfoot videos.
The people who claim to have had close encounters with Bigfoot say that there is no way this creature could be a bear. Bears can walk on the hind legs, but they are not bipedel. Bigfoot is bipedel (walks upright). Bears don't throw rocks; Bigfoot does. Throwing stones is a characteristic of primates.
