Extraterrestrial Evolution: The Intergalactic Worlds of Heaven and Hell in the Eyes of Earthlings

In this speculative evolution scenario, both Heaven and Hell, as depicted in Hazbin Hotel and Helluva Boss, exist not in a metaphysical realm but as two distinct and vastly contrasting planets in a star system far removed from our own. They are worlds teeming with their own unique ecosystems, diverse capable of sustaining life forms both fascinating and terrifyingly alien to anything we know on Earth. Heaven, as we would call it, is a planet radiant with ethereal beauty, its landscape dominated by breathtaking sky cities floating above vast forests and shimmering seas. The resident angels, rather than being spiritual beings, are highly evolved extraterrestrial life forms with genetic traits that provide them longevity, perhaps even biological immortality. Their dazzlingly brilliant forms, perceived by humans as the result of divine providence, are actually natural evolutionary adaptations that enable them to harness and manipulate the abundant energy contained in their sun-drenched world. These angels possess strikingly advanced technology that they utilize for various purposes, including interstellar travel. One of their most controversial practices is the yearly expedition to planet Hell for exterminations, conducted under the guise of controlling the demon population levels. Extraterrestrial exorcists, these hunting parties are feared and despised in Hell. Still, the exact motivation for these hunts - whether for trophy collection or maintaining some cosmic balance, remains a heated debate. Hell, in this scenario, is a stark contrast to Heaven. It's a dark world of magma oceans, towering volcanoes, and verdant poisonous forests punctuated by fortress-like cities of industry. The resident demons are robust and ruthless, forged by the harsh conditions of their world. They consist of three primary species, the lithe and agile imps, the seductive succubi, and the fierce hellhounds. Despite their fearsome appearance and instinctive savagery, they are sentient beings with their culturally complex society. Like their counterparts in Heaven, demons occasionally travel to Earth via advanced spacecraft. Some do so for hunting earthly humans, not for sustenance but as a test of skill and strength. Others, more disturbingly, abduct humans for genetic experiments, cruelly modifying them into the immortal hybrid beings known as sinners. Despite their separate evolutionary paths, both angels and demons have developed genetic manipulation technologies, turning humans into extensions of their own kind. This, combined with the strangeness of these alien worlds, likely contributes to the confused human interpretations of the afterlife in popular culture and religious texts. Finally, it's important to remember that both Heaven and Hell are vibrant ecosystems in their own right. They boast a wide array of plant, fungi, and animal life, some of which have evolved in tandem with the angels and demons themselves, mutually shaping their worlds into the peculiarly captivating realms we think of as Heaven and Hell.
