If there's one person I would want to be the first to offer up real proof on film of the existence of the Abominable Snowman (aka Yeti), it would be David Attenborough. The 88-year-old naturalist, best-known for his award-winning series of nature documentaries and a voice as recognizable as Morgan Freeman's, recently revealed his ambition to take a stab at finding the legendary creature. 

"There is still a mystery about the Abominable Snowman," he told reporters last week at a television network event. "There are teeth that were found back in the 1920s, huge molar teeth about six times the size of ours, immense things, they were found in a Chinese druggists store and undoubtedly are the teeth of a giant ape that must have lived relatively recently itself and that could have been the Abominable Snowman."

Attenborough's interest in the Yeti come as Christie's is auctioning off the first purported photographic evidence of the creature's footprints, taken during a British expedition to Mount Everest in 1951. In describing the tracks, Explorer Eric Shipton claimed they were 12-13 inches long and from a very large animal. 

"They seemed to have come over a secondary pass at about 19,500 ft, down to 19,000 ft where we first saw them, and then went on down the glacier," he wrote. "We followed them for the better part of a mile. What it is, I don't know, but I am quite clear that it is no animal known to live in the Himalaya, & that it is big."

In the interview, Attenborough stated that while he's not sure the Abominable Snowman exists, he's also not sure it doesn't.  

"I don't say I necessarily believe in it, I'm saying that there is evidence and of course one of the very difficult things ever to do is prove a negative, to prove that it doesn't exist," he said.
