If there is a Bible verse to prove that would you please post it?
Have you read the books of Enoch? Even if you don't consider them original writings of Enoch but inter-testamental Jewish writings, they provide the concepts from the Jewish perspective. Both Jude and Peter followed that knowledge. Jude even after making his statement about the angels that sinned quotes directly out of 1 Enoch chapter one. In Enoch it is clearly presented that 'evil spirits' are the spirits of the giants and mighty men, the nephilim. They are the spirits of the offspring of angels, not fallen angels themselves.
You also have the parable of the wheat and tares. The tares are the 'seed of Satan' sown into the same field as the 'son of man'. That field is referenced in the story of Balaam and the talking donkey. Do some research on the 'Field of Zophim', ie 'Field of the Watchers' that is on Mt Pisgah. Oh and btw, Pisgah is a reference to a sex act with 'mother earth', the goddess Asherah. A 'field' in Hebrew is an idiom for 'the womb'. It is the place the seed is sown whether that seed is a plant seed or a human/angelic seed. Watchers are fully defined in Enoch but also attributed in scripture. One scriptural reference to watchers are of women with wings like a stork, ie angelic or at least, winged beings.
In Gen it is the 'seed of the serpent' in conflict with the 'seed of the woman'. In Isa 14, the 'fiery flying serpent' is the fruit/child/offspring of the cockatrice. This is the same passage that calls Lucifer 'ben Shachar' and Shachar is another Canaanite deity that is called a 'son of El' and mentioned in Job 38 as the individual that shakes the wicked from the skirts of 'the earth', ie Asherah.
Even the ancient Babylonian equates two individuals among the pagan gods as the 'adudicators'. They are Hadad/Adad, the thunderer and his son Shemesh the sun god.
Proverbs 9 is a good scriptural reference that equates demons as spirits of the dead.
Pr 9:
13 A foolish woman is clamorous: she is simple, and knoweth nothing.
14 For she sitteth at the door of her house, on a seat in the high places of the city,
15 To call passengers who go right on their ways:
16 Whoso is simple, let him turn in hither: and as for him that wanteth understanding, she saith to him,
17 Stolen waters are sweet, and bread eaten in secret is pleasant.
18 But he knoweth not that
the dead are there; and that her guests are in the depths of hell.
The Hebrew word used here for 'the dead' means 'shades/spirits of the dead' and states their abode is Sheol but they are demons that infest her house. She is following the pagan ritualistic sexual practices of the Baalim worship. Those demons are specifically called 'spirits of the dead', NOT fallen angels.
Then of course you have Peter's reference to Tartarus.
2 Pet 2:
4 For if God spared not the angels that sinned, but cast them down to hell, and delivered them into chains of darkness, to be reserved unto judgment;
5 And spared not the old world, but saved Noah the eighth person, a preacher of righteousness, bringing in the flood upon the world of the ungodly;
Note Peter ties this verse about the angels with Noah and the flood. This is a reference to the pre-flood angels that sinned. The Greek word used for 'cast down to hell' is the ONLY reference in scripture to Tartarus, the 'lowest hell' that in the Greek was the prison of the immortal Titans of the previous age. In the Greek, the Olympians where on the side of right and helped to imprison the evil Titans and locked them in prison in Tartarus. Only the most wicked individuals were asigned to this area of Hades in prison. Why would Peter use the term Tartarus unless he is equated the Greek immortal Titans to the pre-flood angels that sinned?
Now the passage that many people use to suggest a rebellion of 1/3 of the angels is from Revelation.
Re 12:4 And his tail drew the third part of the stars of heaven, and did cast them to the earth:
These 'stars of heaven/sky' are not Yah's heavenly host but what the OT calls the 'hosts of heaven/sky' that are part of the pagan worship. It has MANY references. Here are a few.
De 17:3 And hath gone and served other gods, and worshipped them, either the sun, or moon, or any of
the host of heaven, which I have not commanded;
2Ki 23:5 And he put down the idolatrous priests, whom the kings of Judah had ordained to burn incense in the high places in the cities of Judah, and in the places round about Jerusalem; them also that burned incense unto Baal, to the sun, and to the moon, and to the planets, and to
all the host of heaven.
Note who they are linked with the sun god, moon goddess, Baal, and the planets (Mercury, Venus, Mars, Jupiter, ...) the pagan gods.
And all the events after the start of Rev 4 are FUTURE events, not past events. That event takes place DURING the tribulation. It is NOT a reference to some pre-adamic mythical rebellion.
I can go on and on giving many references. Even the name Lucifer is a Latin epithet of the pagan sun god that equates the the Greek epithet Pheobus as in Pheobus Apollo, or Apollyon the king of the abyss. Lucifer is NOT some mighty fallen angel but the pagan sun god who we would commonly know as the Greek god Apollo, the son of Zeus. Zeus was the Satan cast down 'as lightning'. He was Adad/Hadad, the thunderer that was the 'adjudicator' along with his son Shemesh (sun god). Zeus was the Canaanite Shachar, 'the Morning' that Lucifer is the 'son of'. The 'stars of heaven/sky' that Lucifer was setting his throne above was not to take Yah's authority but to take over his father's role as adjudicator, ie Satan.
Don't forget that dominion over the earth was given to MAN in the garden, not to angels. Isa 14 classifies Lucifer 'as a MAN'.
Isa 14:12 How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations!
13 For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation, in the sides of the north:
14 I will ascend above the heights of the clouds; I will be like the most High.
15 Yet thou shalt be brought down to hell, to the sides of the pit.
16 They that see thee shall narrowly look upon thee, and consider thee, saying,
Is this the man that made the earth to tremble, that did shake kingdoms.
Realize he is on earth trying to elevate himself. Not in heaven being cast down.
Why is it that people pull verses 12-15 totally out of context and ignore the very next verse and the rest of the prophecy? Oh, and the word translated as 'heaven' is Shammayim. It means 'heavens/sky'. The above passage is just as valid to be translated as 'I will ascend into the sky' as in a reference to the Tower of Babel, not Yah's 3rd Heaven. This passage is about the shameful king of Babel being cast down and dying then descending into hell. This is a rebellion on earth, not in heaven.
