Perhaps those of us who have sufficiently evolved morally to be equal to them within our brief lifetimes, will be invited to have that stunted lifespan corrected?

When you think about it, it's Christianity in a more plausible form. (apologies for the heresy). This comet being a ship coming like a thief in the night, certainly would justify secrecy, but ultimately the revelations are unstoppable, if this is the case.

As I say - a tiny tiny outside chance, but non-zero. And it kinda fits with a lot of clues.
