Outline the method for dating rocks and fossils using radioisotopes
And OE Christians (theistic evolutionists) see no problem with this dating whilst still accepting biblical creation, see Radiometric Dating - A Christian Perspective.
This is the crucial point: it is claimed by some that an old earth supports evolutionary theory and by implication removes the need for biblical creation.
This statement is possibly surprising in view of the fact that almost any modern writer can produce a geologic timetable [based on evolutionary theory applied to "index fossils") that gives precise datings and lengths of the eras and systems and even of some of the smaller subdivisions . These figures have been obtained in various remarkable ways. ]"Ultimately, however, they are tied to three [radioactive] dates based on atomic disintegration: (1) 60 million years, the age of the pitchblende at Central City, Colorado; (2) 220 million years, the age of the pitchblende at St.
This just goes to show that just because independent estimates of age seem to agree with each other doesn't mean that they're correct - despite the fact that this particular argument is the very same one used to support the validity of radiometric dating today.
337–348 (2003) and is reproduced here with the permission of the Creation Science Fellowship of Pittsburgh ( The conventional scientific view typically expressed today is that the earth is about 4.6 billion years old and the universe between 10 and 20 billion years old.
These estimates are based primarily on the abundances of parent and daughter radioisotopes and the implications of stellar and cosmological models.
His result was in close agreement with his estimate of the age of the earth.
The solar estimate was based on the idea that the energy supply for the solar radioactive flux is gravitational contraction.
