"Billions of years of radiodecay have occured. This is what the measurements show."
Some of the measurements. C14 measurements of fossils, coal, and diamonds show the opposite. The measurement of Helium escape from Zircon crystals indicate that the radioactive decay occurred quicker than the radioisotope measurements indicate.
I agree that certain measurements show the earth to be very old. But also certain measurements show the earth to be very young. All to often, in textbooks and in popular media, only the measurements showing the earth to be old are used, and they pretend as if they are the only measurements in existance and they all agree.
Yea because these things aren't billions of years old!!

This is a common myth. http://www.talkorigins.org/faqs/helium/zircons.html

A lot of measurements have been made up to claim the earth is young, but many of them are based on incorrect information. Including: -Earths shrinking magnetic field -Rate of salt depositation in the oceans -Helium escape from the atmosphere
