What evidence most supports the existence of bigfoot?

It is sad to note that the physical evidences presented by believers of the bigfoot theory like footprints or tracks, hair that does not match any known animal hair samples, and even scat or droppings not known be that of any carnivorous animal do not conclusively prove the existence of Bigfoot. Even the photographic and video evidences have been dismissed as inconclusive. The various reported sightings of the creature, though undoubtedly large in number, have also been brief or fleeting and did not permit the would-be witnesses to really take a close unimpeded look at the bigfoot. It is these very sightings, though, that have lent credibility to and perpetuated the legend of the bigfoot. It may very well be the one evidence that will bear out its existence.
