The New Testament: Almost complete destruction of the Earth by otherworldly beings?

"1The Revelation of Jesus Christ, which God gave unto him, to shew unto his servants things which must shortly come to pass; and he sent and signified it by his angel unto his servant John:"

"13And the sixth angel sounded, and I heard a voice from the four horns of the golden altar which is before God, 14Saying to the sixth angel which had the trumpet, Loose the four angels which are bound in the great river Euphrates. 15And the four angels were loosed, which were prepared for an hour, and a day, and a month, and a year, for to slay the third part of men."

"14And I looked, and behold a white cloud, and upon the cloud one sat like unto the Son of man, having on his head a golden crown, and in his hand a sharp sickle. 15And another angel came out of the temple, crying with a loud voice to him that sat on the cloud, Thrust in thy sickle, and reap: for the time is come for thee to reap; for the harvest of the earth is ripe. 16And he that sat on the cloud thrust in his sickle on the earth; and the earth was reaped.

17And another angel came out of the temple which is in heaven, he also having a sharp sickle. 18And another angel came out from the altar, which had power over fire; and cried with a loud cry to him that had the sharp sickle, saying, Thrust in thy sharp sickle, and gather the clusters of the vine of the earth; for her grapes are fully ripe. 19And the angel thrust in his sickle into the earth, and gathered the vine of the earth, and cast it into the great winepress of the wrath of God. 20And the winepress was trodden without the city, and blood came out of the winepress, even unto the horse bridles, by the space of a thousand and six hundred furlongs."

"1And I saw another sign in heaven, great and marvellous, seven angels having the seven last plagues; for in them is filled up the wrath of God."

"The Second Seal: War

3And when he had opened the second seal, I heard the second beast say, Come and see. 4And there went out another horse that was red: and power was given to him that sat thereon to take peace from the earth, and that they should kill one another: and there was given unto him a great sword.

The Third Seal: Famine

5And when he had opened the third seal, I heard the third beast say, Come and see. And I beheld, and lo a black horse; and he that sat on him had a pair of balances in his hand. 6And I heard a voice in the midst of the four beasts say, A measure of wheat for a penny, and three measures of barley for a penny; and see thou hurt not the oil and the wine.

The Fourth Seal: Death

7And when he had opened the fourth seal, I heard the voice of the fourth beast say, Come and see. 8And I looked, and behold a pale horse: and his name that sat on him was Death, and Hell followed with him. And power was given unto them over the fourth part of the earth, to kill with sword, and with hunger, and with death, and with the beasts of the earth.

The Fifth Seal: Martyrs

9And when he had opened the fifth seal, I saw under the altar the souls of them that were slain for the word of God, and for the testimony which they held: 10And they cried with a loud voice, saying, How long, O Lord, holy and true, dost thou not judge and avenge our blood on them that dwell on the earth? 11And white robes were given unto every one of them; and it was said unto them, that they should rest yet for a little season, until their fellowservants also and their brethren, that should be killed as they were, should be fulfilled.

The Sixth Seal: Terror

12And I beheld when he had opened the sixth seal, and, lo, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood; 13And the stars of heaven fell unto the earth, even as a fig tree casteth her untimely figs, when she is shaken of a mighty wind. 14And the heaven departed as a scroll when it is rolled together; and every mountain and island were moved out of their places. 15And the kings of the earth, and the great men, and the rich men, and the chief captains, and the mighty men, and every bondman, and every free man, hid themselves in the dens and in the rocks of the mountains; 16And said to the mountains and rocks, Fall on us, and hide us from the face of him that sitteth on the throne, and from the wrath of the Lamb: 17For the great day of his wrath is come; and who shall be able to stand?"

"27For the Son of man shall come in the glory of his Father with his angels; and then he shall reward every man according to his works.

28Verily I say unto you, There be some standing here, which shall not taste of death, till they see the Son of man coming in his kingdom."
https://biblehub.com/kjv/matthew/16.htm

"41The Son of man shall send forth his angels, and they shall gather out of his kingdom all things that offend, and them which do iniquity; 42And shall cast them into a furnace of fire: there shall be wailing and gnashing of teeth. 43Then shall the righteous shine forth as the sun in the kingdom of their Father. Who hath ears to hear, let him hear."
https://biblehub.com/kjv/matthew/13.htm

"30And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory. 31And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other."

"36But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only. 37But as the days of Noe were, so shall also the coming of the Son of man be. 38For as in the days that were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noe entered into the ark, 39And knew not until the flood came, and took them all away; so shall also the coming of the Son of man be."
