Personally, I like Ron Wyatt's claim better. He says that Jesus' blood dripped directly from the Cross through a crack formed by the earthquake onto the Ark, which had been placed underground there centuries before by Jeremiah. He goes on to say that the Ark remains there to this day.
Neat theory, but neither gentleman could be described as an authority on the matter.
Michael Rood and many others have this same theory. Makes a lot of sense, although I can not prove it. I am also sure it (Ark) will not be discovered until the proper time.
