Mandela effect has been going on since the 90's when
Steven Gibbs was selling HDR units, and they do turn our timeline into a mess. However, the Mandela effect is hard to prove.
Let us say you wake up one morning. All your computers and cell phones are gone. After turning on your ancient B&W tube TV, you find out that there never was a Concorde jet and we never went to the moon.
Telling people about the other timeline is not easy. Like they ask you. "Hey, you say we had Concorde super sonic jets in the 60's and none now."
You reply. "Ah, gas was too expensive."
They said. "Jets use jet fuel not gas. Also, the price of oil is less now than in the 60's if you factor inflation in. If we had super sonic jets in the 60's we would have in the other timeline hyper sonic ones now."
Also, you tell them that in 1969 we went to the moon. They reply that if that was true, in the 80's we would have gone to mars. Also, we would be going to now to the stars.
Needless to say, no one would believe you. That is because the truth does not make any sense. It just is.
Throughout ancient history, truth sayers do suffer, while official court historians (liars) do prosper. Kings like stories where they are heroes, and their enemies zeros.
Debunkers take the party line and portray their opponents as morons. Often they constantly change their story as new evidence moves in. Fact is, they do not realize big changes are coming. Always I predict winter in the middle of summer. Debunkers claim that people who believe in snow are crazy. They have never seen any.
For example, a wall mart moves into a small town and I predict that the local
Hanks Hardware store will go out of business in less one year. Debunkers giggle and say - that store has been in business over 100 years you moron. People are not going to turn their back on Jack to save some pennies. I just talked to Jack and he says you are a nut case. He has no plans to close down ever. In fact, he just promoted his son. Why don't you admit you were wrong? Everything you say is wrong. A year later Hank's Hardware is gone. The debunkers say - that was obvious, Hank was 85 and had health issues. I always knew they were going to shut down and you did not tell me anything new.
Lies have to make sense. Otherwise, they would not fool any one. However, for the truth, that is not the case. In fact, lies often are logical, but the truth itself can appear way beyond absolutely preposterous and its speaker a grinning moron or a raving maniac.
Truth is a luxury governments cannot afford so they lie to you. Few people if any wake up. Those that do are labeled crazy.
First they ignore it, then they laugh at it, then they say they knew it all along. --Alexander Humbold
