Here are a few verses from the Book of Noah. In this book these beings are called Angels, but they sound a lot like aliens to me.
6-6 And they were in all, two hundred who descended on Mt. Hermon....
8-1 And Azazel taught men to make swords, and knives, and shields, and breastplates....
8-3 Semjza taught enchantments,
Armaros the resolving of enchantments,
Baraqijal astrology,{astronomy}
Kokabel the constellations,
Ezeqell the knowledge of the clouds,
Araqiel the signs of the earth,
Shamsiel the signs of the sun,
and Sariel the course of the moon.
There are more listed but you get the idea. These are the same entities listed in the Bible as the ones who took wives of earth women and spawned giants. It seems they had a Prime Directive like Star Trek and weren't supposed to interfere in the affairs of humans.
