NASA in this video says that we will discover alien life within 20 years!  That is pretty astounding and there are some who may feel we have already seen them with abductions or flying saucers.

From wikipedia here is some info on the direct search for aliens:

Scientists are directly searching for biosignatures within the Solar System, carrying out studies on the surface of Mars and examining meteors that have fallen to Earth. At the moment, no concrete plan exists for exploration of Europa for life. In 2008, a joint mission by NASA and the European Space Agency was announced that would have included studies of Europa.^[107] However, in 2011 NASA was forced to deprioritize the mission due to a lack of funding, and it is possible that the ESA will take on the mission by itself.^[108]

Let’s find out how NASA thinks we can find aliens in the video on page 2
