4.54 billion years
The current age estimate accepted by most Evolutionists for the Earth and our solar system is 4.54 billion years, plus or minus 0.02 billions years. What is this based on?
This estimate was deduced from the ratios of different lead isotopes found in meteorites . By other means, the oldest age estimate, to date, for an Earth rock is 3.96 billion years (Slave Province, Northwest Territories, Canada). The oldest age estimate for a meteorite is 4.6 billion years.
According to a leading expert:
EVOLUTIONARY AGE AND COMPOSITION OF THE UNIVERSE
13.7 billion years
Data from the Wilkinson Microwave Anisotropy Probe (WMAP) satellite was analyzed to estimate the age of the universe at 13.7 billion years since the “Big Bang”.
The expansion rate and size of the universe are estimated by the red-shift of light coming from distant galaxies. Brightness of supernovas in the most distant galaxies are dimmer than predicted. Hence they are considered further distant than predicted. This is thought to indicate that "the universe's expansion is speeding up" [Ibid, p. 34]. A “dark energy” has been proposed to power this acceleration. This energy is thought to be 73% of all energy in the universe.
23% of all energy is calculated to be nonbaryonic “dark matter”. This unseen stuff is needed to keep star clusters and galaxies from dispersing over multi-billions of years. This leaves only 4% left for baryonic (normal) matter that we can see through telescopes.
