The only way I could back this up is from the reference of the storekeeper, "Those skeletons showed up out of no where", meaning they are not originally from the underground, and Papyrus's armor. It is the symbol of the Starmen in EarthBound. Sans from what I gained, is a Psi user that used a time device, which destroyed his organic body. References of this are from the True pacfist run when you investigate San's lab. OMG SANS IN NOT NESS PAPYRUS IS NOT A STARMAN SCREW YOU GAME THEROY YOU RUINED THE GAME!!! I hate people saying things like fandoms and theories "ruined the game".

Undertale is exclusively singleplayer. Nothing about the game was changed in any way by that theory. How would something not affecting the game's gameplay, music, visuals, or story "ruin" anything?
