Hi, Reserve! Welcome!
I believe that a believe in evolution started with the rejection of the written Word of God.
Where do you get that? Many of the "naturalists" of the early 1800's - the guys who came up with what we now know as geology, palaeontology, and biology - were Christian ministers. But they
followed the evidence they found in rocks, fossils, and life, and realized that parts of their scriptures were metaphorical. Not false, not rejected, but metaphor. Like Jesus's parables are metaphorical.
We have yet to find more at the quantum level to see how this actually works. Currently we have no way to tell which atom will decay. As well, we do not know why the half life works the way it does. For instance, why does one atom decay very soon, and another will not decay for a billion years?
And we don't fully understand how the gravitational attraction of the Sun keeps the Earth in its orbit, or why the angular momentum of the Earth should keep it spinning like it does. Do these failures in understanding cause you to question calendar dating? Will you say, "The Norman conquest might not have been in 1066, because we don't know if gravitons exist or not?" I doubt that you would.....
However, there is current research being done to find out if radioactivity could have increased in the past (i.e. at creation, or during the flood.
Increased how many thousand-fold? If the rate of decay increases, the radiation and resulting heat increase in proportion. How much boiling will an ark of gopher wood withstand? Particularly if it's boiling rock?
And what evidence shows clearly that there was no global flood?
All of geology since about 1815.
