Do space-aliens, also called extraterrestrial life, exist? The Vatican’s Chief Astronomer says that if they do then that happening would not contradict the Bible and it be a part of God’s big Creation.
What was attributed to extraterrestrial acumen (know-how) is becoming debunked by modern archaeologists and modern builders who are able to replicate ancient engineering and construction approaches.
A Russian astronomer reveals that early UFO sightings in the Soviet Union came from classified A/B testing of different monitoring ‘sky-nets’ (that is, testing one system against another) to see which could spot intruders from the air.
So officially, the scientific community does not believe aliens have visited Earth though it is a strong chance there is life out there in the universe. Scientists believe that believing that there could be life elsewhere in the universe is a good way to appreciate our own Humanity.
