The theory is simple.
You have a severe nut allergy. You've decided to make some lunch and in your own folly didn't read the "may contain traces of nut" label and ate a nut infested sandwich. As a result you have a life changing experience where you release that god exists and he's the biggest dog on the block. Alternatively you decided to go get KFC, because you went with KFC, you don't have the same experience and still remain an atheist. There are two different timelines which continue to exist at the same time but at no point overlap - unless of course your now christian counterpart decides to explore that theory further and create a fucking machine that allows you to leap between different timelines
Disconnect and self destruct, one bullet a time.
