"Coincidence?" Adam asks. Or, is it concordism at its best? Case
dismissed.

Hi ASA
The following link covers work by James Kasting on the Earth's earliest
atmosphere...
http://www.psu.edu/ur/NEWS/news/snowballearth.html
According to his figures 0.01% of the current levels of atmospheric oxygen
would have oxidised methane in the early atmosphere. This caused a large
cooling episode for the Earth because the continents of the time were around
the equator and a reduction in the greenhouse effect caused by the methane
meant large sea-ice caps formed. These spread unhindered to the equator and
froze the Earth. A similar sequence of events occurred perhaps four times
between 750 - 570 million years ago.
The relevance? Well many concordist scenarios require obscuration of the
heavens to explain day/night prior to sun/moon in Genesis, but a layer of
continuous cloud cover is unlikely to have persisted for billions of years.
Methane in the upper atmosphere however would've been UV processed into a
layer of "smog" similar to that which covers Saturn's moon Titan, and this
would've done the job. Its demise is correlated to the appearance of
continents collected at the equator and life arising on land almost exactly
the sequence recorded in Genesis...
coincidence?
