“Organic molecules delivered from extraterrestrial materials may have played a key role in supplying building blocks for life on Earth,” said one scientist.
DNA ingredients just means organic chemistry. Which, sure, is awesome and critical to explaining our origins, but “seeded from space” has fuzzy open ended implications. Our DNA itself, what with all its specific protein building instructions, wasn’t seeded from space. It’s like we found ink and pages in space, but we didn’t find shakespeare. The writing happened on Earth.
