Why nukes, which of course we know what would happen, at least to us and most of the species, on it. Yet Earth seems to regenerate itself, -albeit -perhaps differently next time around.
This feels a lot like the old Greek mythology when someone gave man the secret of fire, and the gods angered by all this, "punished" him by chaining him to a cliff, where an eagle would come and devour his liver forever.
By this Time, If ETs know how to give a red signal, then they should also know our propensity to be contrarian, even to our own interests and well being.
Therefore, "they" know they are wasting their breath, or whatever they use for lungs.I didn't see any signals for any cataclysmic event natural or manmade. Whether war, the Holocaust, that Tsunami, or those China syndrome events in the Ukraine. Nor for the production of biological and genetic weaponry and foodstuffs, , which if they are somehow "related" genetically, or rely on the same substinance, should be of some really serious concern to 'them'. I don't think they really care less, if they are there at all. Those of us concerned with the grand issues of our time, climate, disclosure, peace and war, famine, etc, and who dread each coming day, in fear of this very fragile thread we live on and call existence, can only speculate, and of course , will interpret just about anything as a sign from them or God, or God dressed as them, or them dressed as Gods. Its a primal scream for help, from a time the world did seem to revolve around us, and it did. To me, this is all,almost, like seeing patterns in a cloud. We must give things a "meaning".
I know, I know, its depressing, we have to find our own answers. We just want simple answers to the cures from disease, pain, hunger, their technology, and of course the answer to the age old questions when we meet them, "wheres all the womens", and the end to any responsibility at all in making our own way.Perfectly honest, humble and understandable reasons to want to meet "them".
After thousands of years, or just 60 from Roswell, the message if anything should be, don't worry about us, take care of your own selves. Which they,if they are out there, are letting us do admirably.
