I don't know. The bigfoot I saw flying on the anti-gravity device looked like the famouse BF filmed creature.After seeing it(mind you it was carrying a dead dog that was dangling on the left side) i began researching this phenomenon and found pictures from a video of the same exact thing I saw, but only in NEW MEXICO.
We can never know that these things are not aliens.
After seeing the flying Humanoid threads from a google search, you may see a connection.Please do research this area.
Also, to liven up your curiosity, look for / New Crowned Face On Mars.
also look for TUBE FORMATIONS ON MARS.
These pics look like the great saint Louis arch. There is a Bigfoot /arch connection.
El Chupacabra could very well be an alien/bigfoot.
Years ago ...Black helicopters and cow mutilations held the front pages. These all may be connected. The BF could very well be a soldier of some type.Would be freaky to think that they are here to plot our extinction or to eat our brains.
Mind you that I have an open mind to any and all possibilities. Until there is proof....we just do not know.
