Sorry, yes, "unambiguous" is a ridiculous bar. I'm still searching for unambiguous signs of intelligent life on earth. But for "intelligent" life, highly varying non-random radio signals would be a strong sign (i.e. the sort of thing SETI was looking for).

But that's pretty interesting

Quote
In the Archean eon (4 to 2.5 billion years ago), a disequilibrium existed via the coexistence of carbon dioxide, nitrogen, methane, and liquid water, which ordinarily would react to create ammonium and bicarbonate, quickly removing the methane from the atmosphere without the presence of life to replenish it

Now I can see how you could detect possible life without radio signals from a technologically advanced society.

AFAIK, we're searching for signs of carbon-based life.  Roddenberry once mulled over the possibility of silicone-based life forms. Everything else in Star Trek seems to have happened , so why not silicone aliens?
