If I believe it exists, it does.
If I do not believe it exists, it still does, if nowhere else but in the mind.
Thought exists therefore Bigfoot exists.
I suspect no one can prove or disprove an actual walking around, sentient Bigfoot.
Being that we are “floating in space” on a mote of space dust heated by a giant fireball in the “sky” with no idea how any of us got here, why we are here or wtf this “life” thing is, I choose the possibility that Bigfoot exists.
The possibilities in an infinite universe are only limited by this finite human mind, which cannot even really grasp or understand the word infinite.
Like Einstein reportedly said:
“We don’t know shit.”
