Abstract
Appropriate physical conditions for the origin of life could exist on the relic regolith grains. A regolith of this type could be formed on the entire surface of the Earth under the effect of space factors in the early epoch which was characterised by a strongly rarified atmosphere. In the subsequent epoch with a denser atmosphere and suitable conditions for the first occurrence of liquid water droplets such grains had to acquire a considerable biochemical activity.
