yeah to me it implied another biosphere that got destroyed but apparently the other argument is all these amino acids easily form just in nebulas and stuff which means it isn’t direct proof of alien life but otoh if it’s true life in the whole galaxy may be extremely common.
like if all the complex ingredients are everywhere and it formed on earth the instant conditions were suitable, that says a lot. it’s entirely possible if not likely that mars, venus’ atmosphere, and several of the ice moons have/had at least microbial life.
one of the things that bugs me about exobiology is the base assumption is always no life despite all the evidence pointing towards the fact it’s probably incredibly common.
Very cool, but let's be clear here... 14 of the 20 amino acids essential for life AS WE KNOW IT.
Obviously we need to make some rational estimates, so we "assume" extra terrestrial life would look something like life on Earth, but we do not know that as fact.
'In the beginning, the Earth was barren. I named one of my kids after that. It was beautiful. Then the illegal immigrant amino acids from space came in and ruined everything. They came in and started life here.They ate all the pet rocks. It was a disaster. We're going to put a stop to all of it!'
It’s not the only element necessary for life that has been found. These amino acids tho are stuck in a rock. No proteins found. Signs of development beyond the building blocks is what would be groundbreaking.

Dear Aliens....I know you know that I know...so I guess you'll just have to abduct me now. Take me with you!!! 🎟👽🥳👽

I may have misremembered, but I thought rats, for example, could get by on only 12 amino acids.

Human fetus… not so much.
