This is how I feel as well. Some will say it would be so obvious by now we would have seen some sort of indication but then I think of all the planes that crashed without a trace and we have not been able to find even with an idea of where they were flying. The universe is huge. We have no idea how they will try and communicate maybe it's not something as obvious as radio transmission but maybe they have figured out quantum entanglement communication or something beyond our means but super obvious and useful to species who have figured it out. I grew up watching all the Star Trek shows. I have to believe the universe is filled with other civilisations waitin to talk with us.
