Here's one claim about Ron Wyatt, who died in 1999:"One of his more recent excavations led him to find the 'Ark of the Covenant' which is linked to actual site of the Crucifixion of Jesus. This included finding dried blood which when tested, was like no other blood ever found before on this earth. "LOL
In case anyone's interested, the thing he said was so peculiar about the blood is that the cells were still alive, and they had only 24 chromosomes. 23 from the mother, and one Y chromosome.
