I'd expect that you'd have immediately asked which chapter and verse.
It's the *VERY* *LEAST*;
it's not part of being scientific literate, or being of any given religion...
... it's part of having CURIOSITY and being capable of CRITICAL THINKING.

Speaking of passing comets:
Did you know that we've crossed with another comet 3 weeks ago? The closest approach was on August 15, 2011. And it came TWICE AS CLOSE TO EARTH THAN ELENIN WILL on its closest approach.
That's comet Honda-MP. http://en.wikipedia.org/wiki/45P/Honda%E…
Why didn't you feel its passage?
