we only need to look at our own history… humanity are experts at exterminating things that are no threat. you’ve never squashed a bug just because you could?

however the second any of it becomes a threat we wipe it out.

alien life would be no different, civilization always wants to expand but there is a finite amount of material. It ultimately always becomes a competition for resources and we would be wiped out just to not be a competitor.

Having read the Remembrance of Earths Past trilogy i firmly believe we don’t want to make contact.
