Obviously forumites are too stupid to post a picture of a idiot saying aliens.
Your move
Basically an intelligent Grey Goo thing, but purple. And it formed a civilization and was going to be revealed to be all of the planets in the galaxy and stuff but I got bored after trying to write it and ending up explaining everything that happened in the history of the universe.
I had an idea for a scifi concept where certain planets are actually eggs of a massive species of wandering eldritch space-whale abominations that swam through space eating everything. The eggs would be layed in the goldilocks zone of solar systems with all the necessities for development of life. The life would act as an incubation timer and the cthulhu-space-whale children would only hatch once life had developed and reached a critical mass after the unborn space-whale finished developing. When the whales hatch they would devour the eggshell and all life in a cataclysmic hatching and after wiping out whatever potential civilizations had developed on the planet surface then the whales would proceed to eat
everything else nearby-planets, stars, rocks, errythang.
A species of sapients on such an egg worship the spacewhale lurking inside the planet as a god.(Imagine an alien culture similar to the predators) When a faction of the race learns of the whale's mindless intent to devour everything they hold dear, and realize the only reason they exist as a civilization was to act as a first meal for a potential devourer of the universe, then they erupt into a civil war over their continued worship of the spacewhales.
The heretic faction ultimately decides to halt the hatching of the planet-egg by genociding all other life on the planet's surface, including all the dogmatic followers of the spacewhale cult. The surviving faction then sets out on a galactic hunt of other such egg-planets with the intent of total eradication of life on the eggplanets to halt as many other hatchings as possible, no matter the cost.
I think it's kinda creative, but if there's already massive planet-alien concepts out there, then maybe not.
