assuming ID is true, there is still no way to 'know' at what point(s) the designer was directly involved. for all we know, the designer could have front loaded reality, like winding up a clock and walking away. the designer could have snapped his fingers and caused:
Origin of scientific laws
Origin of Universe - big bang.
Origin of Solar system.
Origin of Earth.
Origin of single celled creatures - chemical evolution (abiogenesis or biopoesis).
Origin of plants and multi-cellular organisms.
Origin of fish, animals, insects and reptiles.
Origin of man.
in one fell swoop.
But the ID people say they can see design in living organisms. Why not study the design to see how it was done?
Think of it, studying the mind of god in the tail of a bacteria.
