my opinion story

There has been videos going around YouTube about conspiracy theories. Now there are a bunch of theories but the most popular one is the Mandela effect. Its when a big number of people have a memory of something but when you look back at it, it never happened. Basically the Mandela effect is based around Nelson Mandela and how everyone thought he died while he was in prison in the 80's but was later announced he died in 2013. Now there is a book called English alive published October 1 1995 where it states that nelson died July 23 1991.
One of the theories on why this is happening is that we believe that someone went back in time and changed a minor thing making a bunch of little things change now. In reference to the butterfly effect where Ashton Kutcher went back in time and dropped a pencil and when he went back to the future there were things that were different.
A few of the examples are the Bernstein bears. Its a children's book with a family of bears. A lot of people remember the book being spelled B-E-R-N-S-T-E-I-N bears but if you look at the books or shows its spelled and pronounced Bernstain bears. A bunch of people were saying how its stein not stain. one guy went through his books and found one that had steins. people said it was a glitch in the universe and stuff like that. another example is star wars. Everyone knows the line ''Luke i am your father." its one of the main main lines from the movie. its on t-shirts, posters, its even on other TV shows and movies. If you go back and look at the star wars movie the line is "i am the father." it doesn't even say his name. last example I'm gonna explain is one of queens songs. a lot of us are familiar with the song "we are the champions". Everyone who knows the song remembers the lyrics being "no time or losers,'cause we are the champions...of the world." but nope. there is no 'of the world' it just ends at champion.
A bunch of people could be referring back to the parallel universe or the time traveling theory because they don't understand how million of people can remember something being one way and it be totally different. There are a bunch more examples like the kitkat, chic fil a, monopoly man, or sex in the city.
personally i think the time traveling make the most sense because years ago we thought wed have time traveling by now so i believe we will have time travel in the future. If we do have time travel then that means They are able to go back to now and even before.
