The problem with that should be obvious. Mold does not detonate nuclear weapons, emitting gamma rays into deep space, nor does it have an RF noise bubble out to 50 light years. An optical survey of our atmosphere would demonstrate techno-signatures. Any observers in NEO would see city lights and pick up radio stations. Radar observation would reveal aircraft.
