Why writing it down? It's just religious faith-based nonsense.
Unlike any of the various Raptures, the Singularity is a technological event, caused by ordinary humans, doing ordinary science, building ordinary technology which follows the ordinary laws of physics. It does not involve any religious or divine powers. It doesn’t involve outside intervention by superior or alien beings. And it’s completely within our control as a species- it will only happen when we go out and make it happen. Your claim isn't logical.
