I don't care what Einstein believed in. To a certain degree we all believe in all of sorts of ideas even though we can't prove them. They are just ideas, though, can't be proven, at least not now, you have to live in the real world, you can't live your life based on ideas.
Well, that is your idea. Sometimes you have to get the idea in order for you to understand or atleast know the possible mysteries that this world have.
Knowing the ideas doesn't mean you have to live with it. You just need to open those doors. You might have no interest on that aspect but(looking for answers for any mystery is just an amazing thing and a part of the real world). Everyone is here for a great purpose not just because you were injected by your father to your mother
