It often amuses me to consider just how naive humans can be in
advertising their presence in our spiral arm for a long time now.
Why do so many assume that an advanced race might have such a benign
attitude to other intelligences. We probably don't even share DNA
so why should we seee things in the same light.
See Larry Niven's "Tales of known space" (about 1966) for an example of
a race that got more than it bargained for when it met the Kzin through
radio.


So we should wrap the earth in a Dyson sphere to make sure none of
those evil ET's do us harm?

Yours and others phobia do make for great movies though.

Lets think about it.

Any "evil" ET's that were advanced enough to find and destroy us
wouldn't likely need to find our radio transmissions to find us. The
earth has plenty of cues that there is life here. And any aliens who
could physically come here would be able to find those clues.
