Are you talking about a color variation of a marmot or an uncatalogued lichen or an 8 foot primate that hasn't the sense to use tools, fires, shelter or clothing, and hasn't been found, killed/hauled in/photographed in 400 years of determined human exploiters/hunters/killers/explorers/scientists/hikers/game wardens/naturalists/photographers/loggers/drillers/fossil hunters/roads/vehicles not to mention disease, natural death, predators, accidents, intraspecies competition/stuggles, grizzlies, forest fires, volcanoes, landslides, avalanches, exposure, drowning, heatstroke, hives, lice, dysentery, measles, smallpox, malaria, typhoid fever, valley fever, Lyme disease, scrub typhus, tuberculosis, meningococcus, influenza, streptococcus, staphylococcus, parasites, ringworm, scabies, cancer, heart disease, birth defects, and boating accidents, in this continent?
Because if you are suggesting that the latter, the 8 foot primate, is still "waiting", then you need to recalibrate your probability meter, not to mention replacing your critical thinking fuse.
of course, that's just my opinion. I realize that certain entrepreneurs, liars, hallucinators, substance abusers, attention seekers, 8 year olds and others may disagree.
