If this is true, this further illustrates how retarded these people are.

God's plan is not negotiable UNLESS he says it is and actions are done to obey.

PS There are various impact simulators around. Here's one where you can plug in the type, size, and speed of your space rock and see what would happen: https://janus.astro.umd.edu/astro/impact/

And another: https://impact.ese.ic.ac.uk/ImpactEarth/ImpactEffects/

For reference, here is the asteroid he talks about: https://solarsystem.nasa.gov/asteroids-comets-and-meteors/asteroids/apophis/in-depth/

Not enough to do what he describes. However, that doesn't mean a shower of them wouldn't, or that "Apophis" is not a specific rock but a description of the result, or that NASA would tell the whole truth about a hazard.
