OMG, first of all, GET A GRIP.
Secondly, it was a sarcastic joke meant to debunk the false heliocentric model of the universe that we've been taught. According to godless scientism, stars are light years away. According to the Bible, they are NOT. Naturally, they will fall immediately and arrive promptly to Earth, and Jesus won't have to wait on a freakin' thing. If the heliocentric model were correct, He would need to wait "light years" for the stars to get here. I am merely showing up anti-biblical scientists for what they really are. Sheesh.
