in a story im writing im having a problem with where the disease originates from i can think of three possibilities 1. its a punishment from God. 2. a meteorite crashes into the earth bringing with it the disease 3. this one i dont want to do but its the typical scientist were working on some way to cure some disease and it gets leaked into the air and starts turning people. im wanting to do either the first or second one. the question that im asking is are any of these, mainly the first two, believable? i dont want any type of discussion over whether or not God is real on this post if you reply make it about the question im asking not your views on religion.
