What if we have been lied to protect us, would you want to know not knowing it breaks truce?  Have you seen any evidence from the moon? What did they find and why haven't we been encouraged to go back?. Maybe what they found was so profound that should we dare trespass the future of the human race would be impacted for ever.  Imagine a city the size a quarter the moon inhabited by species of a galactic nature, surely you noticed a few of their ships and abductions we failed to report.
