If us humans came into contact with a life form not from Earth, I think most of us would say that would be an extraordinary finding. With the billions of people on this planet, there would probably be some people who'd think that they would be a threat to us. Really, who's to say that they wouldn't be a threat. Either way, I'm sure some scientists would try to convince us to try and capture these newly discovered life forms. Scientists would probably want to study them and see how they survive in space. That's what I think would happen.
