I believe in UFO's but a different view. I am Christian- it says in the Bible there will be strange heavenly changes, it could be darkness of evil?, or God's angels watching us closer now because of the "time" of our earthly end times.Plus it also could be part of God's plans to have heavenly being close to help us in the end. Look it up in the Book of Revelation in the Bible. Also look up the word Rapture- But I am waiting and not assuming it's good or evil until they show their true colors.
