I'm pretty sure OP got downvoted because he asked a question he could have easily answered himself by looking up the definition of the word in question.

He didn't present a theory at all. He just asked a question about terminology.

The definition of a crater has nothing to do with climate change.

I thought there was some "interesting" conspiracy theory thatI'm not aware of about how we are being bombarded from outer space but it's being covered up.
