Are we looking for alien life in all the wrong places? Even with the SETI project, we are only scanning a limited number of frequencies in a very small window of space. If we are truly are a type zero civilization then we might not even notice a alien communication if we intercepted one. A message sent from a type three civilization would be far more advanced then we can even imagine at this point in time.
Do you believe alien life will ever be found? How advanced will they be?
