My doubt lies in the lack of evidence...why do people never find a bigfoot corpse? No bones, skulls etc? All this time yet nothing. No real solid video or pictures, just a bunch of theories and hopes. Hell at this rate you have a better chance of finding a vampire.
Their all over North America, 1000 lbs, and 8 ft tall yet nobody can ever provide anything but claims and shoddy pics and videos that prove nothing.
