No, that's a ridiculous statement. Firstly, since Uranium, in all of it's isotopes, is radioactive, you can NEVER find a sample that is absolutely pure Uranium.

Evolution is a demonstrable, scientific fact. We’ve seen it happen with our own eyes with mayflies and other short-lived species.

Adaptation is Evolution. Evolution is where a thing changes to better suit its environment.
The only difference between so-called micro-evolution and macro-evolution is timescale. Life evolved over billions of years.

Well clearly because no one has lived the millions of years required to witness such drastic changes. It took about 20 million years for the Eohippus to become the Mesohippus, about 20 million years for that to become the Hipparion, and then about 20 million more for the Hipparion to become the Horse. About 60 million years in total there.
We've got a lot of fossils that are pretty old that are the ancestors of stuff that wanders around today but who are noticeably absent from the modern world (no Eohippus's around after all), and vestigial structures within many lifeforms (including humans) that are holdovers from some previous evolutionary step.
It is isn't faith. It is a fact that life as we know it today came about thanks to evolution.
I think it's pretty cool personally.
