By virtually requiring a common ancestor for ALL terrestrial life, RNA and DNA almost irrefutably support evolution. They are no simple monolithic element of inorganic nature that species can discover and ingest or absorb, but complex assemblies found IN ALL SPECIES (viruses included) yet NOWHERE ELSE. Inheritance is thus the only reasonable explanation* for all places R/DNA does and does not occur, which mandates a universal common ancestor for all species (excepting that ancestor.) All that applies to an even greater degree with genes exclusively composed of R/DNA. The curiosity is that the same observed facts almost mandating a universal common ancestor ALSO almost mandate the first universal common ancestor began supernaturally:

R/DNA NEVER arises in non-living matter, and each species has R/DNA in common with others. Proteins and, later, amino acids have been synthesized, and more recently found naturally present in inert matter, but no more: Individual amino acids, not thousands or MILLIONS of them organized, bound and twisted together in a long, tight and self-replicating spiral. Yet the first universal common ancestor could not have inherited R/DNA (else it would not be first) nor had it transferred from another species (else it would have had no pre-existing R/DNA into which to incorporate new R/DNA.) So the first universal common ancestors R/DNA must have originated in it, which is impossible for inert matter, and all events beyond the natural are SUPERnatural by definition.

*Even mere gene transference (i.e. not inheritance) only occurs between PRE-EXISTING R/DNA structures: Humans can incorporate R/DNA from a virus, but a rock or glass of water cannot.
