For instance, there is also the case of the hominid The date was rejected by paleoanthropologist Richard Leakey.

He already believed that the rocks underneath the volcanic layer had to be between 2 and 5 million years old, because the australopithecine and mammal fossils found in them indicated such an age to him according to his pre-conceived evolutionary ‘model’ or timeline.

Rocks that have been observed forming in recent times have been radioisotope dated, and the resultant ‘dates’ were greatly inflated when the laboratory wasn’t first informed of the Sometimes long-age-believing scientists admit that radioisotope dating has significant problems and weaknesses.

In their view this is mainly to do with the great difficulty in finding rock or crystal samples that have not been weathered, altered, or derived from older rock.

Long-age radioisotope ‘dating’ can’t change wildly by hundreds of millions of years, according to geologist’s changing opinions, and still be considered a true, empirical method of dating.
