"lol, i like the idea of a communist alien, very clever, theres also the possibility they are completely different from us, like being peaceful, i cant think of any logical reasons for any supposed actions they have taken, perhaps they wish to conserve our planet and its life, maybe they arnt just interested in us but are interested in plants/wildlife and studying that aswel and perhaps protecting it(since its most likely unique), perhaps we now know where the last dodo's went...."
hippie aliens? even if that is right, the best way to protect earth, is to have most the humans off it, or in zoos
vortox, i really dont think they are going to be too different. Life only started on Earth, maybe mars too. So there can only be a certain amount of conditions.
Looking at different types (not neccesarily species) of animals
insects - cant grow very big, tend to swarm an area and then die out when there is no food so wouldnt become the dominant species
sea creatures, unlikely, cant get technology without hands and cant take over much of a world, space travel would be VERY hard
mammal - would all end up basically the same as humans anyway (such as from Planet of the Apes"
dinasour tpye of thing - very low intelligence, no chance of getting into space
single celled crap - no chance of getting into space
i cant see any animal apart from humanoids that could get to space
