do u believe in aliens,ufo (unidentified flying objects) ?

There were many unexplained incidents in our country concerning unidentified flying objects. A red orange ball in between two mountain ranges; a humming sound you can't identify while driving on a country road; and mostly the objects appears from nowhere and it's gone before you blink twice. You can't explain it and neither your friends and neighbors can. So, you have to be rational in other aspects like, the universe is too vast and far too wide that we can't claim it as our own. I believe we are not the only species God made to live in this universe.I believe too that they are far more intelligent than us because how else can they travel on such high speed spacecraft and not be detected immediately! I believe there is an amount of truth in Star Wars and Star Trek.

I have recently just seen a red glowing orb at night time, it was big like the size of a hot air balloon but it wasn't because the glowing part was on the very bottom as I could see the outline of it I was outside talking to my neighbor when we saw it and she has had her own sightings even claiming to see a UFO parked out in a field which she said she just kept driving and didn't stop. I was walking down the street one evening in the summer and saw this small bronze looking disc fly right over me (no more than 100 feet up) and strange part was I knew to look up just in time to catch it, it went past me about 20 mph without any sound whatsoever in a diagonal and kid walking in front of me seemed oblivious to it as he didn't look up to see it
