Is there anything in the Bible about UFO's or other worlds that have human life?
UFO's yes:
Deuteronomy 1:32 Yet in this thing ye did not believe the LORD your God,
Deuteronomy 1:33 Who went in the way before you, to search you out a place to pitch your tents in, in fire by night, to shew you by what way ye should go, and in a cloud by day.
Angels travel in metallic crafts. They don't have wings and fly like most believe. These crafts are called whirlwinds, chariots and horses in the bible. Ezekiel has the best description although you have to understand that this man knew nothing about advanced technology or machines and he had a difficult time describing what it was that he saw.
Ezekiel 1:4 And i looked, and, behold, a whirlwind came out of the north, a great cloud, and a fire infolding itself, and a brightness was about it, and out of the midst thereof as the colour of amber, out of the midst of the fire.
Eze 1:4 And I looked, and, behold, a whirlwind came out of the north, a great cloud, and a fire infolding itself, and a brightness was about it, and out of the midst thereof as the colour of amber, out of the midst of the fire.
Deu_1:33 Who went in the way before you, to search you out a place to pitch your tents in, in fire by night, to shew you by what way ye should go, and in a cloud by day.
Psa 68:17 The chariots of God are twenty thousand, even thousands of angels: the Lord is among them, as in Sinai, in the holy place.

Ezekiel 1:5 Also out of the midst thereof came the likeness of four living creatures. And this was their appearance; they had the likeness of a man.
Ezekiel 1:6 And every one had four faces, and every one had four wings.
Ezekiel 1:7 And their feet were straight feet; and the sole of their feet was like the sole of a calf's foot: and they sparkled like the colour of burnished brass.
Ezekiel 1:8 And they had the hands of a man under their wings on their four sides; and they four had their faces and their wings.
Ezekiel 1:9 Their wings were joined one to another; they turned not when they went; they went every one straight forward.
Ezekiel 1:10 As for the likeness of their faces, they four had the face of a man, and the face of a lion, on the right side: and they four had the face of an ox on the left side; they four also had the face of an eagle.
Ezekiel 1:11 Thus were their faces: and their wings were stretched upward; two wings of every one were joined one to another, and two covered their bodies.
Ezekiel 1:12 And they went every one straight forward: whither the spirit was to go, they went; and they turned not when they went.
Ezekiel 1:13 As for the likeness of the living creatures, their appearance was like burning coals of fire, and like the appearance of lamps: it went up and down among the living creatures; and the fire was bright, and out of the fire went forth lightning.
Ezekiel 1:14 And the living creatures ran and returned as the appearance of a flash of lightning.
Ezekiel 1:15 Now as I beheld the living creatures, behold one wheel upon the earth by the living creatures, with his four faces.
Ezekiel 1:16 The appearance of the wheels and their work was like unto the colour of a beryl: and they four had one likeness: and their appearance and their work was as it were a wheel in the middle of a wheel.
Ezekiel 1:17 When they went, they went upon their four sides: and they turned not when they went.
Ezekiel 1:18 As for their rings, they were so high that they were dreadful; and their rings were full of eyes round about them four.
Ezekiel 1:19 And when the living creatures went, the wheels went by them: and when the living creatures were lifted up from the earth, the wheels were lifted up.
Ezekiel 1:20 Whithersoever the spirit was to go, they went, thither was their spirit to go; and the wheels were lifted up over against them: for the spirit of the living creature was in the wheels.
Ezekiel 1:21 When those went, these went; and when those stood, these stood; and when those were lifted up from the earth, the wheels were lifted up over against them: for the spirit of the living creature was in the wheels.
Basically he sees a saucer shaped craft that was made of shining metal with "eyes" all around it which are windows. It has "legs" that have no knee joint which are straight metal landing pylons which support the craft when on a solid surface. It doesn't have a head like an animal that has to turn and look in the direction it wants to go. Rather, it simply moves in the direction without needing to look there first as all kinds of crafts Ezekiel knew of would have to do. This was a round object and there simply wasn't man made crafts like that back then. I believe he is describing what we know of as a UFO yet it is not piloted by a race of aliens that came from a different planet but by angelic beings.

Zechariah 6:1 And i turned, and lifted up mine eyes, and looked, and, behold, there came four chariots out from between two mountains; and the mountains were mountains of brass.

Zechariah 6:3 And in the third chariot white horses; and in the fourth chariot grisled and bay horses.
Zechariah 6:4 Then i answered and said unto the angel that talked with me, What are these, my lord?
