I think what you are seeing is an example of creation "science."
Please do not confuse this with real science.
I have a lifetime of education in Science. The only time I remember “proof” being offered up was in Mathematics.
In Science we deal with evidence (facts) that supports or detracts from a theory.
As such Evolution through natural selection has evidence that fills entire floors of libraries with journals like “Molecular Evolution” or “Evolution” including “Nature” and many others.
‘Evolutionism’ as defined by our mutual FRiend seems to be “evidence that was not twisted to comport with my ideas of what the Bible says and the time-line that I have ascribed Divine inerrancy to”
Yea like what you do assume the earth is old based upon fossils and rocks. Radiometric dating is a science that the people using do not know how to properly interpret, as they believe they know all and assume that nothing can effect the decay properties of specimen.
