[Scp foundation] Given how many world destroying entities the scp contains, why didn't the world end before it existed? And how does it remain secret when it is the size of a major government?

The world has ended at least once.   One of the items is an otherwise identical world in which all life had died apparently through SCP failure.  

Multiuiverse theory being what it is, SCP probably represents one of an infinite string of multiverses.  The ones we receive reports from haven't been destroyed yet.
