[Coyoteman]

Once you understand that diesel engines are made from materials that occur naturally in the natural world, iron for example, and the other materials with which iron alloys to make steel which also exist in nature, when you understand that even petroleum from which diesel itself is derived, also exists in nature, you will understand that it would be unscientific to posit a “Detroit”.

False analogy.

Diesel engines are not self-replicating. (Duh!)

I don’t know, I’ve seen little ones buried in the land fill right next to a couple of big ones.

Diesel engines are not self-replicating.

Man is just the diesel engine's way of making another diesel engine.
