I think Goat-Penguin guy isn't nearly as intelligent as he'd like us to believe. He gives snide and condescending "replies", but no answers, because the only real answer is that stars are not useless points of light on some random black sphere that is somehow suspended around the earth as is hurtles through space, constantly accelerating to produce gravity. The moon isn't a tiny disk spinning about overhead, with no true purpose (or there to stabilize the purportedly much more massive disk of the earth), it's a very large ball of rock orbiting some 380 thousand kilometers away, creating oceanic and atmospheric tides.
I looked at the moon through my friend's telescope the other night, and it appeared to be very round, looking towards the terminator, or horizon of the moon, you could see it's topography, the massive shadows created by mountains and craters large enough to swallow entire states.
Everything up there's got it's uses, Jupiter was in full form as well, watching long enough, you could even see it's moons on their orbits around it's sphere as well.
