- ende 10y agoThe term you're looking for is panspermia. Nothing can necessarily be ruled out but it seems both 1) highly unlikely from a mechanistic perspective and 2) unnecessary to the explanation of life origin.
- asamarin 10y agoThat's called panspermia, and no, it hasn't been ruled out. Main problem with it though is that it doesn't explain how life as we know it came into existence, it simply shifts its origin from Earth to somewhere else
