Like they said in the comic, "what reason would have been satisfying?" ... "Aliens?"Seriously, most of the proposed reasons seem woefully far fetched, there's just no way any virus could reach that many people/animals at exactly the same time planetwide, and a bioweapon wouldn't work without meticulous planning and hundreds of thousands of delivery systems covering the entire planet, which would have been discovered eventually. An ancient Curse? anyone believe in those? nature cutting out the Y chromosome because cloning was almost perfected? seriously doubt it.
I think they may have started out with an idea of what caused it but then realised that any explanation would have been called as bullshit, so they left it open instead.[/B]
It's a story about consequences. The reason for them dying isn't important.
