So, you are saying that because erosion can form a canyon, it’s possible that inanimate molecules can turn into an elephant. Or, that an amoeba might become a camel, given enough time and mutations. That’s quite a non sequitur, AMD. Bob

No, I am saying that one needn't “see” Africa and South America drift apart to gather data in support of the notion that they were once together and did so many years ago.

One needn't see the Grand Canyon form to know that it formed from erosion.

We see the difference between humans and chimps is some 2% in genetic DNA and 6% over the genome. That is as explainable by the observed rate of change as the Grand Canyon is explainable by the observed rates of erosion.

It is only a non sequitur if you think the point I made, and now made again, is not obvious.
