Summary: In addition to the unlikelihood that we have been visited by extraterrestrials, there is no scientific evidence to prove it. Personal accounts are not physical or verifiable evidence. These reasons are sufficient to exclude UFO's from the research objectives of the SETI Institute.

The SETI Institute's Project Phoenix searches for scientific evidence of extraterrestrial intelligence. Investigations of UFO sightings or alien abductions are not conducted at the SETI Institute.

A practical reason for this is that the distance to the star nearest to our own is over 4 light years. That's about 24 trillion (24,000,000,000,000) miles away. With our current rocket technology, it would take around 300,000 years to travel there. This poses a daunting engineering problem even for a more advanced civilization.
