Get used to the fact that some day, history will be measured in BM and AM, M being Mohammed.
BM and Mohammed.
good match.
If it ever comes to that - there will only be AM as nothing which happened before Mohammed matters, or is irrelevant, or is superfluous ... just as any work or idea mentioned in the koran is unneeded and can be destroyed, or any work or idea not mentioned in the koran is anathema and must be destroyed ...
