If a Ferrari can't be made apart from "intelligent design", I don't see how we can be.
A Ferrari isn't alive, nor were any of the other cars that existed before it. Nor do they seek to reproduce themselves.
I'll repeat the last sentence:
Nor do they seek to reproduce themselves.
The reproductive process that life pursues is the base mechanism for change, for variation, that over time leads to Natural Selection, and over even greater time, to Evolution.
The process of reproduction is the process of copying genes to offspring. Simple as that. You mix some of your genes with some of those from a partner, and see what you get. You get a slightly varied form of yourselves.
Do that enough times, and those slightly varied forms diverge far enough from the starting point to represent something different. Yes, they do. (I heard you arguing!)
The variations that work, either by having some survival trait, or merely being "desirable" by potential mates, get passed on. I'm a brown mouse living on the sand, and my girlfriend is a brown mouse. Somehow one of the kids is a black mouse. He don't make it. The owl upchucks his bones and some witch doctor reads them. But he doesn't live to make more black mice.
Unless we happened to move into a lava flow, and all our brown kids would become someone's fortune.
Genes get copied, passed, and once in a while, slightly altered. A bad copy, some missing or changed information. Most of those bad copies don't make it. Some do. If it expresses as something useful, it makes it big time.
Eventually, the divergence caused by those changes is something not like what you started with. The selection process of what works and what doesn't forces a "type" onto the carriers of the genome.
You seem to be able to accept that variation occurs. You also seem to be able to accept that some variations are more successful than others. You just can't seem to make the very simple fundamental inevitable step that enough variation over enough time lets you end up with something - different. It's not that different from its parents, who aren't that different from theirs, but it's much different than what was around 20,000 generations ago.
You also seem to accept that the fossil record exists, and that it shows numerous plants and animals that no longer exist. You just can't seem to make the very simple fundamental inevitable step that extinction is evidence of selection.
