To any culture receiving this message,
Avoid tracking this transmission to its point of origin. The populace responsible for orchestrating this communication is a conscience-conflicted, environmentally irresponsible, conglomeration of 6 billion primitives occupying a precarious, fragile symbiosis with its host planet, and seemingly bent on its own self-destruction.
It is well documented that the last Level 4 sentient emissary who sought meaningful contact with this planet’s highest evolved sub-set, was summarily and brutally executed for merely espousing a simple ideology of, "love thy neighbor as you would love thyself.”
Humans are particularly frightened of any phenomena that are beyond their ability to comprehend. Any challenge to human’s limited perception of truth often results in massive loss of life, and humans now possess weapons capable of extinction level destruction. No other known species builds arsenals of fissionable material, yet aims those weapons of mass destruction at itself.
Some time/space/dimension-faring explorers have had the misfortune of becoming stranded on this cruel, violent world. Humans were very eager and adept at vivisecting any unwary visitors' corpse, and reverse engineering any alien technology they could acquire.
For your own safety, the preservation of this still evolving species, and the prevention of galactic contamination should humans ever obtain faster-than- light technology, if you value the bio-matrix that granted you sentience, please by-pass and quarantine this planet. When humans are truly ready for first contact, they most likely will find you.
