IMO, unless the aliens have invented a spacetime machine and decided to say hello to humans by spawning in a particular location at select time and emit signal strong enough in the direction of earth for the receivers of our tech to detect by present time frame, we would not be able to receive a strong signal.
A civilisation with such advancement and knowledge about our presence in this space time continum would be possibly use tech to sheild us from detecting other civilisation as well. May be life on earth, is a experiment. We are all the subjects
