I don't consider this 'religious' but more Bible based and researched in depth. This includes the KJV and book of Enoch.

I don't even like to use the word alien, extra terrestrial is more like it. Basically any living creature that is not from our earth qualifies. I believe they are creation of YHVH and considered His children, messengers, angels what have you. Earth is specially set aside as it is for us humans. i believe our souls existed in age prior to this one, this is where Lucifer fell and 1/3 of God's children also. In order to salvage His children we have this age and our souls live in the flesh to stand the test of faith. Those thoughts of mine are inspired from scripture throughout the bible.

Angels did indeed leave their habitation to visit earth and impregnate women in attempts to corrupt the adamic seed line that would bring Christ. This all resulted in mutated offspring known as the giants. the fallen ones also taught man kind many forbidden things, this is spoken of in the teachings of Enoch. somewhere in all this either the angels themselves or their offspring are likely to be the origin and inspiration for false gods i.e. mythological greek and egyptian gods.

It is their forbidden teachings that have grown into the self-destructive nature that man has become today.

Book of Enoch

[Chapter 6]

1 And it came to pass when the children of men had multiplied that in those days were born unto 2 them beautiful and comely daughters. And the angels, the children of the heaven, saw and lusted after them, and said to one another: 'Come, let us choose us wives from among the children of men 3 and beget us children.' And Semjaza, who was their leader, said unto them: 'I fear ye will not 4 indeed agree to do this deed, and I alone shall have to pay the penalty of a great sin.' And they all answered him and said: 'Let us all swear an oath, and all bind ourselves by mutual imprecations 5 not to abandon this plan but to do this thing.' Then sware they all together and bound themselves 6 by mutual imprecations upon it. And they were in all two hundred; who descended in the days of Jared on the summit of Mount Hermon, and they called it Mount Hermon, because they had sworn 7 and bound themselves by mutual imprecations upon it. And these are the names of their leaders: Samlazaz, their leader, Araklba, Rameel, Kokablel, Tamlel, Ramlel, Danel, Ezeqeel, Baraqijal, 8 Asael, Armaros, Batarel, Ananel, Zaqiel, Samsapeel, Satarel, Turel, Jomjael, Sariel. These are their chiefs of tens.

[Chapter 7]

1 And all the others together with them took unto themselves wives, and each chose for himself one, and they began to go in unto them and to defile themselves with them, and they taught them charms 2 and enchantments, and the cutting of roots, and made them acquainted with plants. And they 3 became pregnant, and they bare great giants, whose height was three thousand ells: Who consumed 4 all the acquisitions of men. And when men could no longer sustain them, the giants turned against 5 them and devoured mankind. And they began to sin against birds, and beasts, and reptiles, and 6 fish, and to devour one another's flesh, and drink the blood. Then the earth laid accusation against the lawless ones.

[Chapter 8]

1 And Azazel taught men to make swords, and knives, and shields, and breastplates, and made known to them the metals of the earth and the art of working them, and bracelets, and ornaments, and the use of antimony, and the beautifying of the eyelids, and all kinds of costly stones, and all 2 colouring tinctures. And there arose much godlessness, and they committed fornication, and they 3 were led astray, and became corrupt in all their ways. Semjaza taught enchantments, and root-cuttings, 'Armaros the resolving of enchantments, Baraqijal (taught) astrology, Kokabel the constellations, Ezeqeel the knowledge of the clouds, Araqiel the signs of the earth, Shamsiel the signs of the sun, and Sariel the course of the moon. And as men perished, they cried, and their cry went up to heaven . . .

[Chapter 9]

1 And then Michael, Uriel, Raphael, and Gabriel looked down from heaven and saw much blood being 2 shed upon the earth, and all lawlessness being wrought upon the earth. And they said one to another: 'The earth made without inhabitant cries the voice of their cryingst up to the gates of heaven. 3 And now to you, the holy ones of heaven, the souls of men make their suit, saying, "Bring our cause 4 before the Most High."' And they said to the Lord of the ages: 'Lord of lords, God of gods, King of kings, and God of the ages, the throne of Thy glory (standeth) unto all the generations of the 5 ages, and Thy name holy and glorious and blessed unto all the ages! Thou hast made all things, and power over all things hast Thou: and all things are naked and open in Thy sight, and Thou seest all 6 things, and nothing can hide itself from Thee. Thou seest what Azazel hath done, who hath taught all unrighteousness on earth and revealed the eternal secrets which were (preserved) in heaven, which 7 men were striving to learn: And Semjaza, to whom Thou hast given authority to bear rule over his associates. And they have gone to the daughters of men upon the earth, and have slept with the 9 women, and have defiled themselves, and revealed to them all kinds of sins. And the women have 10 borne giants, and the whole earth has thereby been filled with blood and unrighteousness. And now, behold, the souls of those who have died are crying and making their suit to the gates of heaven, and their lamentations have ascended: and cannot cease because of the lawless deeds which are 11 wrought on the earth. And Thou knowest all things before they come to pass, and Thou seest these things and Thou dost suffer them, and Thou dost not say to us what we are to do to them in regard to these.'
