This is a formidable piece of work. Mark Isaac has built an ontology (classification really) of the claims of creationists -- organized by headings such as 'ethics', 'argument form authority' etc.
For each argument he provides a concise and devastating refutation (with contributors acknowledged).
I'd no idea that creationists had such a large and diverse set of attacks. Most are so silly that a rationalist would't reallly register them -- but Isaac avoids that trap. He treats each claim seriously -- and dispenses with it.
Thank you Mark Isaac.
