A great question! While conspiracy theories surrounding the moon landing have persisted for decades, the evidence provided by the original poster is quite compelling. Here's a breakdown of each point:

1. **Lunar Reconnaissance Orbiter (LRO) images**: As mentioned, these high-resolution images taken in 2009 show clear signs of lunar modules and equipment on the surface. This would be difficult to fake, especially given the level of scrutiny and public access to the data.
2. **Chinese Chang'e 2 probe images**: The fact that a non-US space agency was able to capture similar images in 2012 further confirms the presence of Apollo missions' artifacts on the lunar surface.
3. **Retroreflectors**: These devices were intentionally left on the Moon's surface as part of scientific experiments, and their presence has been independently verified by numerous institutions. This would be a rather futile endeavor if the moon landings didn't occur.
4. **Moon rock samples**: The Apollo missions brought back a substantial amount of lunar material (382 kg) that has undergone extensive analysis in various laboratories worldwide. The unique characteristics of these rocks, as studied by independent scientists, are a strong indication that they indeed come from the Moon.
5. **International verification**: The fact that other countries, particularly the Soviet Union during the Cold War, verified and acknowledged the moon landings without controversy lends credence to the events.

While it's true that some details about the moon landing might be disputed or subject to interpretation, the accumulation of these independent lines of evidence makes a strong case for the fact that humans did indeed walk on the Moon.
