Sorry, relativity is against it. They - if they exist (a debate I'm not touching) - don't even know we are here. Even if they knew we are here they can't get here.

Or have a hands-off policy like we do with uncontacted tribes and some protected animal populations etc.

I'll settle for anything to be honest. A sign, a derelict, an artifact, a fossil, an echo.. anything to distract humans from shitting on each other for a little while at least.

Again, physics says they can't. relativite and signal degrigation is hard. the energy of a star outside our arm of the galaxy isn't easy to detect, much less any signal of lower power.

		Our current knowledge of physics says they can't. Who knows what others figured out. We still can't even explain 80% of the mass we measure.
