Topics: Age of the Earth - Wikipedia

The age of the Earth is approximately 4.54 ± 0.05 billion years (4.54 × 10 9 years ± 1%). [1] [2] [3] [4] This dating is based on evidence from radiometric age-dating of meteorite [5] material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.

Following the development of radiometric age-dating in the early 20th century, measurements of lead in uranium-rich minerals showed that some were in excess of a billion years old. [6] The oldest such minerals analyzed to date—small crystals of zircon from the Jack Hills of Western Australia —are at least 4.404 billion years old. [7] [8] [9] Calcium–aluminium-rich inclusions —the oldest known solid constituents within meteorites that are formed within the Solar System —are 4.567 billion years old, [10] [11] giving a lower limit for the age of the solar system.

It is hypothesised that the accretion of Earth began soon after the formation of the calcium-aluminium-rich inclusions and the meteorites. Because the exact amount of time this accretion process took is not yet known, and the predictions from different accretion models range from a few million up to about 100 million years, the exact age of Earth is difficult to determine. It is also difficult to determine the exact age of the oldest rocks on Earth, exposed at the surface, as they are aggregates of minerals of possibly different ages.

The integrity of this ministry has been affirmed by an intensive independent enquiry by eminent citizens (with reputations outside of any sympathy they may or may not feel for CSF or its stance on creation). They chose to investigate all of the serious Plimer allegations, plus a random selection from the hundreds of other ones (they indicated that they had covered about 200 items in some depth) and found them ALL to be without any substance whatsoever and highly misrepresentative of the facts.
