Sounds about right, off the top of my head. I’d imagine that age has been extended greatly, and numerous times, due to the mindboggling amount of time assumed to be necessary for the macroevolutionary “tree of life” to work it’s putative magic. I’m also possibly of a mind that built in age assumptions have skewed methods of measurement as well.
I’m thinking that fossils - mostly marine invertebrates - became a matter of major interest in Europe around the time period I mentioned. However, I don’t know why the existence of different kinds of seashells and stuff implies either billions of years of time OR the evolution of lower life forms to higher.
I do remember starting a book about a British man who mapped geologic strata around the 1850’s (canal-building period), and the statement that various kinds of ammonite fossils “proved” all live evolved from pond scum. One suspects a pre-existing agenda behind this kind of reasoning!
Geology doesn’t have anything to do with evolutionary theory.
