Ah, no need to answer, I would not answer either, if that was my website...it seems that website is geared to get either yours or someone elses campaign off the ground...just was wondering how successful you have been so far...
That website is a steaming pile. It offers this phony challenge, and lists all those who have laughed it off.
If they want to challenge the scientific data and theories, the libraries are filled with journals--whole floors of journals--dedicated to the evolutionary sciences and ancillary fields. That is where the "challenge" must be addressed. And it must be addressed through the scientific method.
Their pitiful little challenge is worthless, as science is not a side show, argued before a gullible audience or a court. It works on the slow accumulation and testing of both data and theory, with scientists as the arbiters of what is accepted. If they have evidence against evolution, they should submit it to one of the many scientific journals.
As Heinlein pointed out years ago:
What are the facts? Again and again and again - what are the facts? Shun wishful thinking, ignore divine revelation, forget what 'the stars foretell,' avoid opinion, care not what the neighbors think, never mind the unguessable 'verdict of history' -- what are the facts, and to how many decimal places? You pilot always into an unknown future; facts are your only clue. Get the facts!Robert A. Heinlein, Time Enough for Love, 1973
