Alternate world

Ever asked yourself: "What if this and that would be like that and this" or "What if that existed" or whatever you get the point. Now you get to figure out. Just say whatever is different in this world from the world we know, and then what you do. Now keep your cursed thought's here and dont bother anyone else with them, i have read things that make me question humanity sometimes. (I just pressed things when it comes to the voice, be like me and don't listen to it. Its probably not worth)
