- senttoschool 4y agoIn the video, they said an impact like that happened an estimated 6 times and each time, life sprung back. The whole surface was sterilized. This makes me think that if life comes back after that 6 times, then it must be pretty easy for life to start.
- phailhaus 4y agoStarting life is very different from recovering it. Luckily none of those asteroids killed all life.
- senttoschool 4y agoIn this particular Youtube video, they mentioned that the object that hit Earth was 500km or roughly 38 times larger than the one that killed the dinosaurs. I could believe that the Earth was sterilized from an impact that large.
- phailhaus 4y agoWhen did it hit though, do we even know if life had started yet?
- krisoft 4y ago> This makes me think that if life comes back after that 6 times, then it must be pretty easy for life to start. Or that they are wrong and the whole surface was not in fact sterilised. Or life survived somewhere other than on the surface (deep underground, underwater, or high in the sky).
- dasil003 4y agoSeems likely that some single cell life could survive in some deep cave system
- readams 4y agoThere may not have been life before that. In the video they just say that if there was life it would have to begin anew.
