Summary:The supposition that the Earth had an oxygen-free early atmosphere is questioned and an alternative hypothesis advanced: that the primitive Earth lacked a condensed ocean, but was surrounded by a moist atmosphere containing small amounts of photolytic oxygen necessary for a UV-protective ozone screen. The formation of simple, primordial organic compounds did not take place on Earth, but at the time and place of the formation of carbonaceous chondrites. [A.C.B.]
