Our nuclear age predated the moon landing, though that doesn't seem to be necessary (this is relevant because radiocarbon dating is impacted by nukes; we should see records of that if it happened).
The moon isn't a static place, though. Meteors slowly change its face, and artifacts may well be buried there. Putting big and durable monuments on the moon would be quite the expensive endeavor, so we'd have to do some significant lunar archaeology to really rule it out.
Ocean floor isn't static, either; stuff gets swallowed by subduction zones on geological timescales. Not to mention falling debris and ocean life tend to build up; I wouldn't expect artifacts from 1Mya to be sitting out in the open.
