Does Life Exist

[Ruatha]

To detect inter-system communication within another system is propably hard.
You have to aim at that system directly, it's not very high signals that would reach earth if the signals aren't directed in a tight beam towards us, I belive. Not to mention that we might be listening on the wrong frequency, if communication is sparse they might not be using that many frequencies. And perhaps there is other way to transmit communication than by radio waves. Wires planetside and light in space? Perhaps mass communication isn't for all species?
What where the SETI resources in the 40:ies?

So to say that we've been monitoring the EM band closely for the Last 70 years isn't the whole truth.

(I might be out on thin ice here as I really don't know but what I've written here seems reasonable, right?)
