Do aliens exist? Almost certainly. The Universe is vast and ancient, and our corner of it is not particularly special. If life emerged here, it probably did elsewhere.
Keep in mind this is a super broad assumption. A single instance of fossilized archaebacteria-like organisms five superclusters away would be all it takes to say, "Yes, there are aliens!" …if we could find them somehow.

Until we can send paleontologists to other galaxies, the best way to search for aliens is to stay at home and look for "techno-signatures."
What are they exactly? Honestly, we don't know, but we can make some good assumptions. For example, when we use radios to communicate, we produce signals that are very different than the natural sort of energy you'd get from a star.
It's reasonable to assume aliens would do the same thing for their communications, so we mainly search for unnatural-looking radio signals from fixed points far away in space.
Radio sensing, or any scientific attempt to detect non-human techno-signatures, can be referred to as the Search for Extra-Terrestrial Intelligence (SETI). SETI efforts are generally led by organizations like the SETI Institute and Breakthrough Listen. Citizen scientists play a key role in analyzing data as it's gathered and sometimes even making their own follow-up observations on possible detections.
So far, several candidate detections have been made, but none have been confirmed. Read More…
