#1 What is the ratio of carbon-14 to carbon-12?

#2 This might not help much, Grimp old man, as carbon-14 to carbon-12 ratios are only good for dating for the last 40,000 years, and not the 3.6-2.8 billion years for the finds mentioned in the article.

The ratio of normal carbon (carbon-12) to carbon-14 in the air and in all living things at any given time is nearly constant. Maybe one in a trillion carbon atoms are carbon-14. Both Carbon-12 and Carbon-13 are stable, but Carbon-14 decays by very weak beta decay to nitrogen-14 with a half-life of approximately 5,730 years. After the organism dies it stops taking in new carbon.

#3 Carbon 12-13-14 ratios are different for diamonds on the moon and diamonds on the earth.

I guess what I am saying is each heavenly body has different ratios for sometimes different reasons. Its too early to use carbon isotope ratios to infer anything on Mars.

#4 But they see "livable planets" light years away. "...billions and billions..."

#5 But they see "livable planets" light years away

I suggest that the Beltway crowd embark on a voyage to visit them to be sure, then.

#6 Fairbanks,
Carbon-12 to carbon-13 then.
