There is no fact that disagrees with Intelligent Design
Now here we have an example of the famous "unfalsifiable" theory.
It would not matter what sort of variety that life forms showed--it could always be attributed to "intelligent design."
This argument is really no different from the old Argument from Design. Notice how the planets revolve around the sun with perfect regularity and order.
This is like saying, everytime I throw a ball into the air, it comes back down. Every single time. There are no exceptions.
Therefore, God exists.
That's really what this ID concept amounts to.
