the parameters of what an extraterrestrial lifeform must be capable of has dramatically changed since the 1950's, where then it was plausible for spaceships to be just like normal rocket craft made by species that can make trivial miscalculations and end up in scotland, but now it wouldn't read at all outside of a comedy for an alien to make a mistake like that because we understand that aliens would have to develop technology well outside our understanding of basic physics to travel to earth #monsterdon
