The problem with radiocarbon dating
And you have to check to make sure he touches the edge at the end of each lap.
Without these observations you cannot be sure that the time is valid.
We note that at the instant the swimmer touches the edge of the pool our wristwatch reads and 53 seconds.
How long has the competitor taken to swim the 1,500 metre race?
Without the starting time it is Actually, knowing the starting time is still not enough.
During the race you have to watch the swimmer and count how many laps he has swum so you know that he has done 1,500 metres.
By 1830 Lyell's famous textbook, Principles of Geology, came out. Such was the age of the great creationist geologists!
The principle of faunal succession in the geologic record was established by direct observation as early as 1799 by William Smith.
If you check this educational page by the US Geological Society you will see that they spend all their time talking about the technicalities of radioactive decay.
Then the paleontologists use the geologists' dates as evidence for the age of the fossils! The relative order of the strata was first determined by the principles of stratification. Beagle, a very strong Bible believer, made it a point to have a copy of Lyell's book for the ship's library.
(The principle of superposition was recognized as early as 1669 by Steno.) Reverend Benjamin Richardson and Reverend Joseph Townsend were a couple of early geologists involved in this work. Obviously, even Lyell was not pushing evolution at the time.
When I have asked an audience this question they have looked at me incredulously and said, “Starting time?
” You cannot know how long the swimmer took unless you knew the time on the wristwatch when the race started.
