Well, I don't know if I would say for sure it's Nephilim, because there were OTHER giants on the earth once upon a time, were there not? Actual finger found, yes. Giant, yes, of course. Looks mummified. Sure, believable. But yes monkey, I agree with you that more of similar findings have been found and covered up over the years. How this one slipped by, who knows. What are they planning, that's my thoughts.
There were most definitely giants on this planet. The Titans of myth, whether or not they are the same beings as the Nephilim, and they may just be, like anything else, one under the names of many over centuries and millennia.
Cool stuff anyway. Real or not, it opens people's minds to greater possiblilities, and maybe they can accept that the fact that creatures of a greater magnitude than themselves were on this planet long ago. I wouldn't be surprised to find out there are some still living here now.
