When the astronauts went to the moon, there was nothing there. They certainly weren't bored.

Because it wasn't just a rock, but the first time entering another natural body of mass in the universe, apart from our earth. Something that never happened before. In contrast, over a million players have discovered planets in Starfield by now, including all customly made content by Bethesda for the planets.
The astronauts where excited and happy as they achieved a huge step for humanity - somewhere I heard that before - while one could literally only achieve one small step for a human in Starfield.
