if all the water on earth came from asteroids, then isnt underwater life alien life forms?

Could that be why we differ from all sea life, because their origins are not from Earth?? or maybe just maybe we all came from somewhere else and just met up here by chance?

No. We have a substantial genetic heritage in common with all aquatic life... some more than others. We share something like 73% with Zebrafish for instance, mammalian water dwellers like whales and dolphins that actually returned to the sea after originally being land dwellers are much more closely related to us.



More or less all life on Earth seems to have emerged from the earliest self replicators - microbial bacteria and archaea - which were present on Earth as early as 3.8 billion years ago, when the relatively young Earth was still an incredibly hostile environment, at least by the standards we'd understand today.





However the jury is still out on exactly how the earliest life forms emerged or where they first occured, so if you prefer an extraterrestrial origin story (bacteria or archaea carried through space from elsewhere - possibly even our neighbouring planets - on asteriod or meteorites) or a theistic one (God made everything) then no-one can yet prove otherwise.

This is beyond the realm of science brother. I don't believe everything evolved by chance, but that would not be reason to stop being curious and learn more about the origins of life.
