The possibilities for the designer, in the view of intelligent design, are virtually infinite because no creator is named. I am not expert, but as I understand it ID makes the assertion (correctlyin my view) that evolution does not explain how life began and does not answer all the question inherent in the fossil record, etc. While this is true, it is very, very long way from Genesis 1 and 2. Thus ID is not a Christian statement.
Again I ask. What can the designer be other than God (Christian or otherwise)?
