Once upon a time, the planets of Neptune, Mercury, Venus, Jupiter, Saturn and others were vastly inhabited. Unfortunately these planets slowly started becoming unlivable for their inhabitants. All planets suffered their own consequences of global warming: Neptune became a huge ball of ice, Saturn started releasing poisonous gasses, etc.

Unable to live on their respective planets, some creatures fled to earth and immigrated on our planet. Later, even creatures from other planets arrived on earth. Once the aliens arrived, they were in awe with our sense of fashion and started to experiment with it.

There was just one thing they didn't like about it: society's excessive need to conform to the binary split between men and women. So these aliens decided to mix it up, and in that way started teaching us humans to let go of the binary norm.
