Yes, because the Moon has no atmosphere. Therefore, apart from the Moon's surface, there is nothing to reflect or refract the light from the Sun. And so, just like the "sky" (a.k.a. empty space) outside the ISS or anything else in space, is black, the sky above the Moon is black.
Again, it isn't really complicated. And beyond the simple reasoning, do you honestly believe that thousands of people participated in this "hoax"? Do you honestly believe that NASA created all of the telemetry, radio transmissions, video recordings, and fake moon rocks (that they brought back), and that they convinced dozens of Apollo astronauts, flight engineers, and the media to go along with it? Do you honestly believe that India is actively participating in the hoax by fabricating photos (50+ years after the fact) of the Apollo 11 descent stage on the lunar surface?
If you're not an idiot, you must at least be wearing a nice tinfoil hat.
Enough name calling—at least have the decency and respect to address the strongest arguments that disagree with you.
