There are events, situations, and individuals that we've come to understand are real, but they have very different accounts around the details. I think a list that lays out the differences would be useful. I know people will immediately want to argue about what's true or not true, so I suggest we focus on listing out all of the variations as a catalogue for future confirmation. Chime in if you agree and would like to add to this collection.
The first example I'll address is Lemuria and Atlantis. We know they were real, but there are different explanations of HOW they were destroyed. These are three that I'm aware of:
FARSIGHT (Atlantis - The True Story video):
Scientists drilled into the center of the Earth that caused a massive explosion.
QHHT Hypnotherapist (Book from A HYPNOTIST'S JOURNEY TO ATLANTIS by Sarah Breskman Cosme):
An imprisoned Lemurian princess activated red crystals to detonate. Before dying she emplanted the story of the civilizations in a girl who fled to where would become the territory of the Vikings and her tale became the origin of Norse Myths.
Johan Fritz and Jodi Reynosa (Journey to Truth Podcast Ep 182):
Dracos known as The Black Confederation destroyed them both using light ships.
