Ken Ham is yet another ex-pat Aussie (think Rupert Murdoch) who is screwing with the country's head!
I saw him on the old, original "Nightline" show with Ted Koppel, when the Creation Museum was opening.
When asked what was his inspiration for the museum, he said, "When I saw that the evidence for evolution was," so strong, or words to that effect, he knew what he had to do. "EVIDENCE!" "What in the lord's name is evidence worth when it, when it contradicts my fairy tale beliefs?" I expect he thought. If "Night line" is archived, the interview ought to be there. Like any self-respecting parasite of the cloth, Ham knew a money maker when he saw it.
This abomination to the reason is in Kentucky, the home of Mitch McConnell, and Rand Paul, just as the Creation museum is.

When the facts change, I change my mind. What do you do, sir? Paul Samuelson, receiver of the Nobel Prize in economics, 1970.
What Ham did was bury his head still deeper in the sand! But, hell, he's making money fist over brain.
