… The Mars photo has to be fake. I can believe a lot, but not that one.
As for Bigfoot, people will laugh but yeah, I think he's real. There are just too many sightings in too many places. Still it does make you wonder why no one can get physical evidence.
… that's easy. the body decomposes quick out in the wilderness and the bones are scattered by animals. the hair gets blown away or made into nest. we have foot prints but that's easily duplicated so people have stopped believing that one but there are still the photos. besides I have seen him once and only for a second.
