Early molecules would have been destroyed by UV light (Talk.Origins)

Claim CB030.1:

Since the early atmosphere had no ozone layer, ultraviolet (UV) light would have irradiated organic molecules that formed in the atmosphere, destroying complex molecules.

CreationWiki response:

What Talk Origins left out is that no amino acids were produced. What were produced were aromatic alcohols, ketones, ethers, and aromatic hydrocarbons. There are plenty of molecules between the products and RNA and DNA that would still be destroyed by UV.

It also needs to be noted that this only works at just a few degrees above absolute zero. While this is fine for deep space, UV will become a problem as near to a star as the Earth is to the sun.

This works fine for DNA and RNA but not their constituent molecules.

It needs to be noted that this is an as yet untested theory. Even if it pans out it would only render this claim out of date. There would still be the chasm between raw RNA / DNA and a living cell, with all its cellular machinery and stored information.

First of all these geothermal vents are known to be as hot as 380 degrees Celsius. However, even if amino acids and nucleotides formed at such high temperature they would not last long. While life does exist near these vents, their organic compounds are maintained by the internal machinery of living cells. However, raw amino acids and nucleotides would not stand a chance. Furthermore, the hot water near the vents tends to rise to the surface, just as hot air rises. So any surviving amino acids and nucleotides would get pushed to surface by heat driven water currents, where they would be zapped by UV.
