I never said that evolution was the only game in town. Both are valid hypotheses (which I've stated over, and over, and over...). However, the usual ID hypothesis does not use a human designer as a premise. You won't get any traction from this fact unless you are positing that speciation was designed by man (and I am pretty sure that is not what you are saying). Just because we've verified that human designers can cause speciation in no way verifies the existence of non-human designers.
I'm not making any claims as to the composition of the Intelligent Designer(s). I'm merely showing that the theory is valid and has supporting evidence for it.
If the proof of Intelligent Design means that God exists, so be it, but that's a bit beyond this pedestrian discussion. If the proof of Intelligent Design means that Man did it, then so be it, but again, that's beyond this discussion.
What I will say is that Intelligent Design has been scientifically demonstrated both in the lab and in the wild. Intelligent Design aligns with the current known fossil evidence and explains some species such as the duck-billed platipus for which other theories seem to be missing evidenciary support at the present.
What other theory explains both modern genetic engineering as well as ancient fossil evidence?
Why support a theory that is inferior to that?!
