Radiometric dating and the age of the earth
Inserting vast ages into the Bible’s first chapter sets it at odds with modern secular scientific opinion regarding the order of events.
Old-earthers put land mammals before whales contrary to biblical claims.
If we look at the earth through the “glasses” of human reasoning—that only snail-paced present geological processes can explain the past—then the earth does indeed look old.
However, that autonomous human reasoning blatantly denies what God’s Word clearly tells us.
A fossil can be studied to determine what kind of organism it represents, how the organism lived, and how it was preserved.
However, by itself a fossil has little meaning unless it is placed within some context.
The age of the fossil must be determined so it can be compared to other fossil species from the same time period.
Coincidentally, this is the same age as the rest of the planets in the Solar System, as well as the Sun.
The slope of the line determines the date, and the closeness of fit is a measure of the statistical reliability of the resulting date.
Technical details on how these dates are calculated are given in Radiometric dating. As with any experimental procedure in any field of science, these measurements are subject to certain "glitches" and "anomalies," as noted in the literature.
At some point in the early history of Earth, a planetoid the size of Mars crashed into our planet.
The resulting collision sent debris into orbit that eventually became the Moon.
