I want to start by pointing out that Einstein was a physicist not a Biologist.
Now, ID suggests a Creator, that does not mean that the Creator did not use evolution to attain the result or humanity.
So, Creationism in the Traditional Christian tradition says that God Created Adam in human form about 6000 years ago. We can safely assume Einstein did not believe that.
One can believe in the precepts of intelligent design while still believing that evolution occurred. Its not one or the other.
Now the fundamentalist Christians specifically do not believe in evolution.
All of this aside, Creationism and intelligent design are not scientific concepts, they are spiritual. Evolution is a scientific concept that might have spiritual implications depending on what you believe.
What scares me is not the ID'ers but those who deny evolution.
