Using logic and reasoning all I can offer as a layman is that a greenhouse canopy type atmosphere would have had different properties than ours which would likely affect the whole ecosystem of the planet which in turn would likely render modern dating methodoly inaccurate. This would likely be the reason that humans lived multiple century lives as per the Biblical record.
I love this argument. Simply because it is so easily refuted. Water (and water vapor) tends to absorb useful light (red, yellow spectra). But water tends to be invisible to short wave radiation, like UV. This is why tourists get bad sunburns on cloudy days. So a planet with a water vapor canopy could not grow plants, and any organisms on the planet would have to adapt to daily doses of lethal UV exposure. But funnily enough, none of these would have an effect on radioactive decay, as these are constant under any planetary conditions and only become important at temperatures such as the heart of the sun.
