I believe... I also believe in Unicorns, Santa being Satan and the Tooth fairy.
I mean this is as cliché as you can get...
Needwork, think about this. You say a Meteor is circling the Earth right. Well obviously if this was true, the meteor would have to be smaller than the Earth for one and for two, the meteor wouldn't destroy the Earth, it would merely leave a giant scar in it.

It's as dumb as Nuclear weapons destroying the Earth. It has been proven that the amount of Nuclear weapons we have now would not even be enough to take down a whole country, let alone the entire planet.
So in that case I don't believe it.
