Lets say for argument sake, this person is actually for real. ok. how else could they prove beyond a shadow of doubt unless they do something no one else could.

Now if indeed an earthquake does hit in the place that has been told and at about that time, what then.

I bet most will go silent, shocked and gobsmacked at being proven wrong.

Then again, it could be a total load of $**** in which case you can say "I told you so"
