I believe these guys are onto something. I think he was not born in the 1800s, but did surface at that time. I believe, no scratch that, I KNOW, that he is what the bible calls the ANCIENT OF DAYS and has walked the Earth for thousands of years.

But I do fear for the lives of those astronauts, because there are most likely more 10-thousand year old serial killers on Mars.
