But there is plenty of evidence posted for the idea that the observed data is best understood as the result of an intelligent cause. Some parts of the curriculum:
forensics showing design
order and physical laws/principles of physics indicating force or a cause maintaining that order at it's root
irreducible complexity
the fossil record
commonality of design in living organisms
fundamental properties of what constitutes the material or physical world
adaptive mutations and other examples of non-random mutations
logic in the origin of intelligence and ordering (goes with point above)
molecular detail (goes with irreducible complexity)
genetic engineering showing intelligent design can and does occur as a concept (does not mean genetic engineering is only method, just one we have discovered)
I suppose you could read the 10 Evidences presented by Jerry Van Bauer for more.
