Not necessarily no. The arrangement of the planets in our solar system today came about because of the nature of the protoplanetary disc as the sun was being formed. They have basically been continuing in the same orbits for 4+ billion years. I'm not sure of your question is more about orbital mechanics or the history of formation side of things

You can ask him to think about the cold war. The soviets independently confirmed the flights of Apollo 8-17, they were listening intently. If there was doubt about the legitimacy of the program, they would have been shouting from the mountaintops. To believe that the Apollo program was all a ruse, you'd have to believe the same about the entire cold war. The tensions with Cuba which last to this day, the Vietnam war, the buildup of nuclear arms - was all of that a sham? In that case, this ruse would have come to encompass so many hundreds of thousands, if not millions of people, that there is no way that a secret like that could be kept for 60+ years.

Shorter answer: the Apollo astronauts left mirrors on the moon. Shine a laser at that spot, it shines back. Shine a laser elsewhere, nothing.
