The amazingly innovative 1930s science fiction author Olaf Stapledon has an invasion from Mars in his epic history of the future of humanity and its various evolutionary stages, Last and First Men. The Martians are a gaseous life form that can come together to sort of form a jellylike mass. They originally think radio signals are Earth’s dominant form of life and everything else is their livestock. That feels much more believable to me in terms of how we would relate to each other.
