As a result, radiocarbon dating isn't so accurate: "Provided they are adjusted, radiocarbon dates are now considered reliable as far back as 5000 B.

Doesn't that give accurate dates of "prehistoric" civilizations?

Carbon dating is the ultimate benchmark of the evolutionary dating world.

Everyone assumes that dates that follow the word "radiocarbon" are accurate, precise and sure. The basic principle of radiocarbon dating is that plants and animals absorb trace amounts of radioactive carbon-14 from carbon dioxide (CO2) in the atmosphere while they are alive but stop doing so when they die.

Anything further back and the dates are as much as 800 years off.

So scientists made calibration charts to make up for the variation.

But they still have to verify their calibrations with samples of known dates. Radiocarbon dates can only be trusted up until the record left by trees can back them up.

The carbon-14 in a sample decays at a steady rate after it dies, and thus works like a clock.

It is assumed that the amount of radioactive carbon left in the sample indicates how old it is. It is based on several assumptions, one of which is false.

For this method to work, the rate of production of carbon-14 in the atmosphere has to remain constant through time.

In truth, however, the amount of carbon-14 in the atmosphere varies with fluctuations in solar activity and Earth's magnetic field, changes in atmospheric conditions and even the exploding of atomic bombs!
