then all we can do is speculate that other hypothetical civilizations might be using similar technology. We don't have much other than speculation to go on. Since we're already listening to the heavens with radio telescopes and observing with several spectra with telescopes, it isn't as if we're going out of our way in the hopes of detecting artificial signals against the background noise.
If other civilizations exist, they may not be at the stage of development yet to use RF communications, just as we weren't until about 100 years ago. On the other hand, they may have passed through this phase of development and be using some other technology unknown to us, just as we'll be doing in the decades to come. For all anyone knows, they may be communicating all around us but we don't know how to listen in, just as a primitive tribe would know nothing about radio or TV signals.
