Maybe. But you overlook that there are those
other civilisations that also come in legions that exist right now and still can be avdanced to us by hundreds of thousands of years - and just have had not the needed time to reach us in communication and that our radio signals have not had the time to reach them.
if we would have an intended target receiver of our message, maybe he would be so far away that he has gone missing when our message finally reaches him in some thousand years. But others who have not been there when we hit the transit button, may pick it up, may reply - and wonder why they never get an answer from us.
Because we will go missing sooner or later, too. - I mentioned the cosmic calender analogy earlier, somewhere above. If the 14 billion years since the big Bang would be scaled to match one regular Earth year, and our present now would represent the 31. Decembre at 23:59:59 hours, then the milky way formed up sometime during February, and the solar system formed up early September. The dinosaurs would have appeared on the 28. Decembre and died on 30. Decembre. Early hominides saw the light of earth on 31.12. at around 9 pm, just 3 hours ago. The pyramides were built 11 seconds ago, and you and me were born around just 1 tenth of a second ago. The dinosaurs died yesterday. In real life, that one day in the analogy is 65 million of our Earth years.
