If the American landing on the moon was a scam, where did his rocket go?

Two days ago, CCTV 10 also made a program on this issue, saying that if this was a scam, American rockets would still fly to the moon, but at that time, because of technical problems, Americans were eager to show their achievements to the world, so they created such a scam. And those things were shot in Hollywood, including a documentary at that time. There are still many problems with the American moon landing. It is said that the rocket at that time was called Saturn V, which was even more powerful than the most advanced rocket at present. But why didn't the United States retain such powerful rocket manufacturing technology, or even drawings? But this is just a scientist's guess. A few days ago, BillKaysing, known as the "father of the moon landing scam", and British photographer DavidPercy wrote "We have never been to the moon".
