[Titus Quinctius Cincinnatus]

Unfortunately for your argument, evolution was known before anyone had discovered genomes. Thus, it is impossible for the former to be a mere assumption invented to explain the latter.

Actually, you've got it backwards. I would assert that genetics (in and of itself empirical) is pressed beyond its intrinsic capability for explanation into the realm of "justifying" evolution through the a priori assumptions made by evolutionists who fit genetics into their already-existing circular reasoning.

Here, we find the root of your misunderstandings. You are basically treating "science" as a sort of cook-book of recipies that have no necessary logical connection to one another. That is, perhaps, sufficient for brewing up potions that will alleviate the common cold without causing the patient to grow a second head, but it will hardly do for the topic at hand.
