The evidence many find persuasive: radiometric dating.
But is radiometric dating really the objective hard science many believe it to be?
 Variances were seen regardless of location: The expectation is that rocks located at the same site would date to the same age regardless of the method used.
From the data above, obviously that is not the case.
But when dated by the K-Ar method, did they get an age of a few years old? The K-Ar method showed the age of the newly formed rocks as between 0.35 and 2.8 million years old. Clearly incorrect. Simply because they have a story to protect, namely that “the earth is billions of years old.” Because if the true age of the earth and universe were determined, the secular religious stories of evolution and the Big Bang would be demolished, having been clearly demonstrated to be false.
