Many institutions , groups , individual amateurs all are watching Universe for evidence of extraterrestrials or UFOs through electromagnetic radiations.
There are substantial number of evidence of UFO cases which has been backed by thousands of credible witnesses.
There are many photos, videos, radar tracking, satellite sensor reports, landing traces including depressions and anomalous residual radiation, electromagnetic interference, and confirmed physiological effects and personal observation has been made both in day and night regarding these so called extraterrestrial.
I stumbled a recent case in sighting of UFO in the year 2008 and is as follows :
Dozens in Stephenville and Dublin, Texas report seeing large UFO
Date January 8, 2008 Location
Stephenville, Texas, United States
Several dozen people — including a pilot, county constable and business owners — insist they have seen a large silent object with bright lights flying low and fast. Some reported seeing fighter jets chasing it. Locals swear that it was larger, quieter, faster and lower to the ground than an airplane. They also said the object's lights changed configuration, unlike those of a plane. People in several towns who reported seeing it over several weeks have offered similar descriptions of the object .
It is being believed that extraterrestrial life in Universe may have effect on religious ideology so the governments always try to cover up the cases of UFO sighting. A question comes to mind that if there is a mass landing of UFO on Earth then would the priests , pastors and other religious heads would address the event to their congregation ? What will happen if we found out these extraterrestrials are more advanced technologically to us or they are atheist ?
