But the amount of C-14 in the atmosphere is dependent of how much nitrogen is converted by radiation into C-14. The nitrogen level could not have been much higher than its current level of 78%. If the radiation hitting the atmosphere is the same. There is the same concentration of C14. But the ratio of C-14 to C-12 is almost 20 times less if ther is 20 times the amount of CO2.

Also the radiation hitting the atmosphere was less before the flood.

Gracie,

I am so proud of you! Yes - you made exactly the same erroneous assumption that the original scientists made:

"If the radiation hitting the atmosphere is the same. "

Sadly - it isn't. The levels of background radiation varies (Cosmic Rays if you want to get technical).

This is why the tree rings were such a God-send (tee hee). With Tree rings we have something of known age. We take a C14 reading from that and can then extrapolate the curve that we use to correct readings.

From the same tree rings we can see that the levels of CO2 in the atmosphere haven't changed dramatically in 11,000 years. We can extrapolate further but we don't use Carbon dating beyond 40,000 years for reasons including the one you mentioned (varying amounts of CO2 in the atmosphere).

The background radiation may vary but not 20 to 1.

The tree rings cannot be used because they cannot correct for the 20X CO2 in the presence of less radiation hitting the atmosphere before the flood.

You also do not have 11,000 years of tree ring history.
