I will concede if a UFO did crash at Rosewell then the govt probably has it and may have even figured out how it worked and all the UFOs flying around now are US pilots testing them out.
As for Bigfoot, Zachary you made a very convincing argument. I beleive there is SOMETHING running around out there, but the one thing that nags at me is how come there aint like a bunch of them running around? At the most people see one. If these things have been around hundreds of years how come there aint a bunch of them running around and discovered by no? Are they asexual and give birth and then die off with the baby left to grow up on its own? Do they have some secret colony that is yet undiscovered? I just think if there are Bigfoots running around that we would have absoulute proof by now because there would be a bunch of them running around and easy to find.
There ARE actually reports of sightings of families or family-like groups of Bigfoots with even a few tales (I'm skeptical) of people being "held" hostage for a few days in a Bigfoot community. Close examination of the famous Roger Patterson film shot in the 1960's seems to demonstrate that the specimen (if real) in that footage was FEMALE, with rather pendulous breasts. The Patterson film has a weird and interesting pedigree and at various times I've been convinced it was a hoax and at one point a man stepped forward and claimed he was the person "in an ape-suit" for the film. He replicated the kind of strange gait the "creature" showed and it seemed a situation of "case-closed". Further analysis and enhancement using computers and detailed measurements though demonstrated that this man COULD NOT POSSIBLY have been the figure in the film and that the relative proportions of limb and body length ratios did not match up to human proportions. Further, detailed enhancement of the film showed an area on the "creature's" leg where apparently the hair had been worn away, showing bare skin beneath and even showed the working of the thigh muscle as the "creature" walked, complete with a bulge that was extremely consistent with a type of herniated thigh muscle rupture found in heavy-set human athletes. These kinds of details go FAR beyond "a guy in a monkey-suit" which this film has been said to be by detractors and such details are impossible even today to do with a "suit", much less it having been possible in 1966. I'm moderately convinced the Patterson film is the real deal at this point and I've ALWAYS, even at my most doubtful times about it, wondered why I've NEVER seen even a professional attempt at creating a Bigfoot hoax look so "real".
There is another video, taken a few years ago of a rather "small" reported Bigfoot, hurrying across a field. This video tape is rather grainy and shows a figure estimated to be about 5 1/2 feet tall, again with a strange gait. What is compelling about the footage is that, while it's pretty grainy, toward the end of the video, as the figure is passing out of the clearing of the field and into some underbrush, it suddenly shifts in a weird way and appear to get about a foot and a half taller. It has been speculated this footage showed FEMALE (based on its small size) and the sudden "increase" in height is thought to be the female shifting a previously hidden infant back up onto her shoulders. Such behavior has also been reported among apes, where a mother wold interpose her body between her infant her a potential predator/threat and otherwise generally carry her baby on her shoulders.
Yeah, I'm VERY troubled by the fact that no bodies have been recovered or other incontrovertible remains. Unidentified hair with primate characteristics are interesting but in the end, just food for speculation. If, though, these creatures do exist, they must by virtue of their description be HIGHLY intelligent--more so than the brightest apes, though clearly less so than humans as they have no "civilization" and live more or less as animals. It's also clear based on their reported reactions to seeing humans that they desperately want to avoid us. Their intelligence and desire to avoid us may be why we haven't found "groups" of them and only catch relatively isolated sightings. They are highly intelligent and are ACTIVELY seeking to avoid us. It's true that there are still large terrestrial animals waiting to be discovered. Every few years or so another gets found someplace. Few of those, if any, are actively seeking to AVOID being found and it's taking us a while to get around to them. In the case of Bigfoot, it may just be he's smarter than the rest and doesn't WANT to be found by us. In most reported instances, rather than attacking or showing curiosity when they've encountered humans, Bigfoots have just run like hell from us. For being "monsters" reports of them attacking are EXTRREMELY rare.
