  The discovery of all five nucleobases on Ryugu suggests the molecular ingredients of life may have been already forming in space billions of years ago. Asteroids may have helped deliver those ingredients to the early Earth – making the origin of life part of a much larger cosmic chemical story.

Why do we think that Earth needed those ingredients from asteroids when the same rocks formed Earth - thus, giving Earth everything it needs without asteroids?

I suppose those don’t survive the “earth forming” part?

But survives a high speed impact from outer space?

		Sure, we previously found all these nucleobases in meteorites like that one: https://en.wikipedia.org/wiki/Murchison_meteorite The Rugyu sample is interesting because it basically rules out earth contamination

It doesn't really matter because in either case, Jesus did it just like he always does.

Very insightful. You get paid somewhere to have that insight?

No. But I interact with people every day who have this as a core feature of their existence. It explains a lot about society.

		Maybe post that as a reply to someone who says something like this instead of making a sarcastic, non-sequitur comment.
