Irreducible Complexity proves there was a "Designer"
The Dover School Board had only to show that "intelligent design" was a "credible theory" to win their case in the case Kitzmiller vs Dover Area School Board argued in Federal Court in Dover Pennsylvania in 2006.
They couldn't even do that. They lost and were severly chastized by the presiding judge.
ID is a default position; a negative arguement. A problem in evolution means it is all no good and there fore Intelligent Design is correct. WRONG.
Supernatural causation cannot be tested as can real science.
