C. S. Lewis’s Space Trilogy has an interesting take on such topics. (Earth being fallen, but other worlds not).
About the only conclusions on intelligent alien life we have enough data to reliably make are: they might exist; they are not common in our own solar system; they have not visited earth in any way that would make detectable traces; they did not tell Hindus about eliminating the dinosaurs with advanced nuclear weapons (the radioactive bones are Jurassic, not Maastrichtian, and nuclear bombs do not produce microtektites or iridium clay layers, gods fighting multi-headed snakes with fire-orbs is not the same thing as aliens nuking dinosaurs); they did not give Solomon a laser pointer to create smooth blocks for the temple (lasers do not work to cut rocks, unless they vaporize them, in which case it’s not a clean cut; a piece of harder rock is all you need to smooth out limestone blocks); they did not build a spaceport at Teotihuacan that had a giant electrical device (big temple) blow up (mica is an insulator, but so is the rock the temple is made of; pyrite is not a great conductor, neither is mercury).
