A creationist says the erector set is NOT self-organizing.
In fact, he/she will notice that the erector set needed:
(1) knowledge of alloys,
(2) strength of materials info,
(3) dimensional tolerancing of parts,
(4) compatible design for distances to interconnect components,
(5) understanding of simple machines (threaded screws, pulleys, etc).
In short, I see the need for a Designer.
There are two ways to try to convince someone of something.
1) You can beat them over the head with your beliefs and tell them they’re stupid if they don’t agree with you
2) You can present them with a set of facts and trust that they have enough intelligence to connect the dots. If they don’t, you’re wasting your breath with either tactic.
You prefer #1. I prefer #2.
