extraterrestrial: coming from or existing outside of Earth.
Are We Being Watched? Government Studies 650 UFO Cases
The US government is studying over 650 potential UFO cases. Sean Kirkpatrick, head of a special Pentagon office, said the number of cases has risen from 350 earlier this year. Some think these could be probes made by foreign governments. Kilpatrick says there is no evidence of extraterrestrial activity. But he does seem open to the possibility of aliens. Last month, he published a paper with Harvard professor Avi Loeb. They speculated that recent UFOs could be alien probes from a mothership sent to study Earth. While they don’t know for sure if any alien probes are near Earth, Loeb is planning to study the possibility.
