I appreciate your comment, but I have to respectfully say this is the kind of lazy thinking I am complaining about. Yes, we have been emitting radio waves for 100 years, but 100 light-years away, how strong are those radio waves? Remember the inverse square law. Even if you magically knew the format, could you decode them? If you did not know the format, could you detect something above the normal bacground? If we did think it was above the background, would we believe it was artificial? NASA has a very high bar for what they think it artificial.
