How can we be sure that it won't happen again, and if you are praying to a god or gods can you be sure its the right one.


Imagine the only people who go it right were the Mormons, every one else hell I;m afraid

Everything happens in cycles and there is nothing mere humans can do to stop that fact.
As for the religious angle, it all depends on your own personal belief system.

The one that answers is the right one. Call on as many as you want, including the god of abraham ,isaac, and jacob. See which one answers. That is if you really want to know.
