Predator Theory

Every animal in know existance has a predator. Why wouldn't we? How could we have a predator? Wouldn't we notice the loss of poeple? You would think that we would notice lets say 300 "attacks" a year. But let's look at the facts, we lose people. They go "missing" and are never seen again. The scary thing is that we lose 800,000 people a year in the U.S. alone. They go "missing." 800,000, just gone... That's not counting reappearences, murders, or runaways. The creepiest part is that the percentage lost to "missing" cases is the same exact percentage as that of animal lost to predators from a herd.
