During the first 5-600 million years on Earth,temperatures ranged from 500-1000°C,atmospheric pressure was 10 times current levels,and the planet was bombarded with meteorites.How would these conditions favor the formation of biological molecules?

A) Oxygen in this high temperature and pressure atmosphere would have been chemically less reactive.
B) Water and meteorite dust would have provided the chemical reactions necessary for formation of biological molecules.
C) Many chemical reactions are inhibited by high temperature and pressure.
D) Oxygen will break down many organic molecules by reduction.
E) High temperature and pressure are the best conditions for enzyme function, needed to support life.
