I once believed that perhaps the Mandela Effect was true, but I would never believe that God could not preserve His word. I learned I was deceived about things in the world changing also, and there are explanations for that. Let’s go over the Bible first because that is the most important.
Why would anyone claiming Satan is changing the Bible use the Bible to prove their theory? None of us have the full Bible fully memorized, so how can they pick what parts were changed? For all they know, they are quoting Satan. They have taken all credibly away from the word of God. If scripture is not infallible, you have rejected the authority of the one who endorsed it.
I was in a group that was promoting this idea, and in the comments, they were also saying that God’s word is an idol. They kicked me out of the group and was told they gossiped me about after I confronted the lie. The antichrist’s lying and gossiping spirit was showing. I often hear this new belief that God’s word is an idol, along with the Mandela Effect theory.
They claim this verse is about the end times:
Behold, the days come, saith the Lord God, that I will send a famine in the land, not a famine of bread, nor a thirst for water, but of hearing the words of the Lord:
Amos 8:11
Amos 8 is about Assyria destroying Northern Israel in 722 B.C. Context is so critical when studying the Bible, or anything, really.
The lion and the lamb were used frequently on Christmas cards. Isaiah 11:6 is speaking of enemies and sin being defeated. The wolf is often used to describe an enemy.
The wolf also shall dwell with the lamb… — It is significant of the prophet’s sympathy with the animal world that he thinks of that also as sharing in the blessings of redemption. Rapine and cruelty even there were to him signs of an imperfect order, or the consequences of a fall, even as to St. Paul they witnessed of a “bondage of corruption” (Romans 8:21). The very instincts of the brute creation should be changed in “the age to come,” and “the lion should eat straw like the ox.”

Regarding Mark 2:22, “And no man putteth new wine into old bottles:”. Every other Bible apart from the KJV used wineskins. Perhaps some people only read the KJV, but we frequently hear other versions quoted. Different words used in translations are extremely common.

Sanctify them through thy truth: thy word is truth.
John 17:17
The words of the Lord are pure words: as silver tried in a furnace of earth, purified seven times. Thou shalt keep them, O Lord, thou shalt preserve them from this generation for ever.
Psalm 12:6-7
Trust in the Lord with all thine heart; and lean not unto thine own understanding. Proverbs 3:5-6
But he answered and said, It is written, Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God.
Matthew 4:4
Now the serpent was more subtil than any beast of the field which the Lord God had made. And he said unto the woman, YEA, HATH GOD SAID, Ye shall not eat of every tree of the garden?
Genesis 3:1
Another example is “if you build it he/they will come” from Field of Dreams. I specifically remember a commercial that played for quite a while saying “he will come” and the movie said “they will come”. The same goes for Snow White and Star Wars. Those two movies have been quotes thousands of times. Snow White has been remade into other movies and books a ton of times.
