Explanation:
RNA synthesis is catalyzed by an enzyme called RNA polymerase. RNA polymerase always catalyze the synthesis of new RNA from 5' to 3' because nucleotides can only be added to an available 3'-OH group on the transcript terminus. This has been confirmed in labeling experiments with γ-32P substrates which establish the presence of a triphosphate moiety in transcripts with either pppG or pppA.

But blue algae are able to perform photosynthesis and so we can believe that the first forms of life on Earth date even further back than 3 and a half billion years ago.
