I don't agree. If we were to find a civilization at approximately our level
of technological development it would be strong evidence that such
civilizations are common but they never get any further; so we must be very
near to a catastrophic planet wide extinction event of some sort.  Although
not as clear cut I would not consider even the discovery of microbes on
Mars to be good news.
