Possible Grounds for the Belief in Extraterrestrial Life

In the ancient world, people speculated about the existence of intelligent creatures in outer space. As our understanding of the universe expanded, so did the possibility of extraterrestrial life. Today, secularists and Christians alike consider the vastness of the cosmos and the likelihood of life arising elsewhere. Additionally, the sightings of unidentified flying objects (UFOs) have fueled speculation about the existence of aliens. While some UFO sightings can be explained naturally, others display flight characteristics beyond our current understanding.
