What is the value of making a claim about what happened a million years ago?
The mining companies I worked and still work for value studies of rocks millions of years old very, very much. So much so that the Geologists they employ are some of the best paid people in the country.

You would need a time machine to validate it.
Nope. The mining companies I work for validate the models about the past, built by the Geologists, by digging down to mine those minerals as indicated by the models. They get mightily upset when they spend billions on digging down to get to those minerals as indicated by the the models and find that those minerals are nowhere to be found.
