I think you may think you know more than you do - I am not afraid to admit anything. ID could expose a designer or it could expose intelligence in the form of seeding from another planet. I call them like I see them and in this context - hopefully - dogma-free (be it the dogma of religion or the dogma of materialism)
"ID could expose a designer or it could expose intelligence in the form of seeding from another planet."
Can't you see this answers nothing. It just removes the question from Earth to another planet. No matter how many seedings you try, sooner or later, you get back to the original beginning.
Then what are your choices?
