A comprehensive Checklist for Sci-Fi writers working on Religion. Free worldbuilding resource from Obsidian Tavern.
Religion in science fiction serves as both a mirror to contemporary beliefs and a laboratory for exploring how faith might evolve alongside technology, alien contact, and cosmic expansion. Unlike fantasy religions that often draw from mythological archetypes, sci-fi religions must grapple with scientific advancement, space colonization, and the fundamental questions of humanity's place in a vast, potentially inhabited universe.

Theological Response to TechnologyHow your religion adapts to, embraces, or rejects technological advancement shapes both doctrine and daily practice.Cosmic Scale WorldviewSci-fi religions must address humanity's place in a universe containing multiple worlds, species, and potentially infinite space.Evolution and SchismsReligions change over time, especially when confronted with paradigm-shifting scientific discoveries or technological capabilities.Ritual and Practice in SpaceReligious ceremonies and daily practices must adapt to alien environments, artificial habitats, and the physical realities of space travel.
Pro tips
✦Consider how your religion's creation myth accounts for multiple planets, alien life, or artificial intelligence—these cosmic scales demand theological frameworks beyond Earth-centric traditions
✦Design religious schisms around technological developments: How do traditionalists react when AI achieves consciousness, or when genetic modification challenges concepts of the soul?
✦Use religious practices as worldbuilding shortcuts—a prayer ritual reveals gravity levels, atmospheric conditions, or the cultural importance of certain technologies
✦Explore how digital consciousness affects concepts of afterlife: Can uploaded minds achieve salvation? Do quantum backups have souls?
Common mistakes to avoid
!Making religions purely reactionary to technology rather than showing how they might embrace or integrate with scientific advancement
!Ignoring the physical constraints of space travel and alien environments when designing religious practices
!Creating monolithic religious responses instead of showing the diversity of denominational reactions to sci-fi scenarios
!Focusing only on how religions change without considering what core elements might remain constant across centuries
!Treating alien contact as automatically faith-destroying rather than exploring how religions might incorporate non-human intelligence into existing frameworks
!Forgetting that future religions might emerge from scientific discoveries rather than just being evolved versions of contemporary faiths
!Underestimating how communication delays and relativistic effects would practically impact religious authority and community across interstellar distances
Remember that the most compelling sci-fi religions don't just add flavor to your world—they actively drive plot, create meaningful conflict, and force characters to confront the deepest questions about existence, purpose, and what it means to be human in an infinite cosmos.
