A better analogy is that no one can accurately measure what the weather was a week ago, or tell when the last hailstorm was, solely by looking at today's weather. Sure there are indicators which give a pretty good idea, but not to the accuracy claimed about the age & origin of the universe.
And yes I know that cosmologists don't really study earthquakes - but they DO use practically the same scientific methods and few ounces of grey matter.
If you have a beef with the claimed accuracy of the measurements regarding the age of the Universe, by all means post the evidence. This thread is over 150 post long, and not a single naysayer has provided a scintilla of evidence that the methods used by the scientists were defective.
