We have now discovered all four building blocks of DNA in meteorite samples, suggesting that space rocks may have delivered the compounds to Earth, contributing to the origin of life
Perhaps the meteorites simply contain the "splatter" from contact with prior life-rich planets. The Earth had life on it before it was geologically stable and there is some speculation that early life had to periodically survive eras without some fundamental component like a stable atmosphere or ready access to water or sunshine.
We'd hoped to find a rich microscopic extraterrestrial biome when we sent probes to the Moon and Mars, only to be disappointed. But that does not rule out the possibility that we were simply too late to the party (or, potentially, too early) to discover what we expected to see.
Does this advance the "seeding" theory of origin as more plausible?
If anything it means that life could be very common throughout the universe we just can't see any of it from here.
That seems more plausible than my idea of dudes shotgunning DNA rocks into space
I like your idea too though ngl
"fuck it, another planet out there somewhere "

it could also just mean that nucleic acids are easy to make under conditions that commonly occur in the universe
