G-d disguised Himself into Snake and tricked the first Humans to eat the apple. This is direct cheat from G-d on to Himself since Human is created like G-d. The story itself is a joke since if G-d can cheat on Himself thus believing in it is also a cheat onto believer.
So, if it simple cheat, why should anyone believe that the story itself is not cheat.
So, when we see that the story itself is a trick to cheat our minds, then we don’t have the ground on which our world is being built.
What is hidden behind that?
So, if this Myth is just a cheat, then we don’t have any reliable source about G-d, Human and how everything was created.
