How about the 'evidence' that the rocks from Mt. St. Helens are 2 million years old?
As others pointed out, there is no evidence that the rocks from Mt. St. Helens are 2 million years old. The dating test was totally inappropriate. For one thing, the error bars on that particular test are on the order of a few million years. In other words saying the dating method gives an age of 2 million years plus or minus 3 million years is the same as saying the rocks are brand new.

What he thought was the human fetal gill turned out to be our ear.
This is exactly what happend. In all vertebrate embryos there is a structure that arises called the pharyngeal pouches, and sometimes called "gill slits". In jawless fish these pharyngeal pouches form the gills. In fish with jaws part of the pharyngeal pouches form the gills and part form the jaws. In mammals part of the pharyngeal pouches form the jaws, and part form two of the bones of the inner ear. The prediction was that part of the jaw of the reptile ancestor, specifically the jaw joint, detached from the rest of the jaw and became the inner ear bones.
This has been confirmed. Fossils of reptile-mammals have been found showing that correct bones of the reptile jaw has detached, and are in stages that are in between jaw joint and inner ear bones.

People try to say that this proves evolution.
The point of the observation is that the environment can have a direct influence on the relative frequencies of alleles. No one claims otherwise. This is a necessary part of evolution, and it has been confirmed. The other necessary points of evolution have also been confirmed in other observations and experiments.
