Yeah no scifi movie about alien invasion ever gave theological reason of Adam's sin as one why they want to kill us. I mean we constantly hear Christians "explaining" us that earthquakes, floods, supernovas, volcano eruptions along with all other natural disasters and animal suffering are because Adam sinned so -if true- aliens must be really pissed at us because they also lived once in the paradise (as whole universe did) until pesky humans fucked it all up.
teachings of the Bible are so muddled and self-contradictory that it was possible for Christians to happily burn heretics alive for five long centuries. It was even possible for the most venerated patriarchs of the Church, like St. Augustine and St. Thomas Aquinas, to conclude that heretics should be tortured (Augustine) or killed outright (Aquinas). Martin Luther and John Calvin advocated the wholesale murder of heretics, apostates, Jews, and witches. - Sam Harris, "Letter To A Christian Nation"
