The term First Contact applies to the moment when we employ a means of communication with alien beings that also have a means of talking back to us. There are several ways First Contact could happen. The most popular idea, originating from the UFO phenomenon, is the image of ET landing on the lawn of the White House and greeting the president. However, scientists hope they are the first to establish communication with ET, via radio signals.
