ADVANCED ALIENS
Is it really pathetic that we are looking for aliens with radio? Do you really think they would be transmitting to us with old fashioned radio? Radio, on Earth, is archaic at 120 years old.
As our sun is young comparatively to other stars in the galaxy by 4 billion years, it suggests that the average alien could be 2 billion years more advanced than humans. A lot can happen in that time span of evolution.
It's very doubtful we would know any technology for the required instantaneous transceiver type devices needed for across the galaxy conversation.
Given that radio travels at the speed of light, and would take one million years to reach one of the nearest galaxies, and another million years for the reply to reach Earth, why would any alien be so stupid as to use that form of communications?
Only Earthlings are so stupid to send a message that would take 50,000 years to answer round trip to and from M13 stars in the constellation Hercules, as we did in the 1970s with the Arecibo radio telescope.
Only an aggressive species like us would use radio, and our location calling card message might be a food menu telling aliens "the restaurant is located here, come eat us."
So let's get off our lazy stupid human arses and invent a form of instant communications for across the galaxy conversations. But really, will the reply be anything we can understand? We will be like unimportant single cell creatures to any alien advanced by 2 billion years.
