exactly, they are not biological organisms capable of reproducing, they are 100% intelligently designed- yet leave an almost identical fossil record to the one used to suggest accidental design improvements
complete with dead ends, large gaps, sudden appearances as if just planted there with no prior history, but a general trend towards greater sophistication.
The model T did not drop the ball, it paved the way
This is a ridiculous analogy...
Model T's are just as viable of a vehicle today as they were when they first rolled off the assembly line. A 2016 Ford F-150 operates under all the same principles as the very first Quadricycle. They literally do
exactly the same thing; propel their occupants from place to place.
Living organisms, on the other hand, don't work like that. If an offspring develops some random gene mutations during their formation (which the parent has absolutely no control over) which leaves them permanently disabled from birth, the parents can't hop over to the "Offspring Mechanic" and have their parts replaced, forever fixing the genetic flaw in their DNA, can they? There is nothing you can do to make that Offspring more biologically fit. Nothing at all. All a parent can do is provide for that offspring the best life possible, which in turn makes the parent's fitness less biologically viable. Even the most broken down automobile can be rebuilt or restored to a fully-functioning, like new condition. No organism can make the same claim.
The only way your analogy works is if you admit that our human-based intelligently designed machines are far superior to anything that this supposed creator has ever produced...
