We could redirect it to hit planets that we don't like. Like Mercury. Fuck Mercury!

God tries to wipe out humanity with an asteroid. Humanity not only deflects the rock, it begins mining the thing.

I've got some advice for the greater forces that be, stay out of our way.

I tought of this vid in the day that rock hit Russia. I tought, shit, he tranquilized me falsely, we are not ready for it.

I say we just pray, and the power of the "all mighty" will save us.

From what does any asteroid or comets come.

[Spaceisprettybig]

So deep impact was the ultimate money shot?

[Zygimantas Bulaitis]

Pretty sure the next time a threat comes we will be able just tu punch a fuck out of it, or move it away within secconds, or somehow use it to our needs.
