Creation.

I think it is easy to forget what memories, reality, science and "fact" really are. Just because you can remember something doesn't mean it's true, just because experimental theory points to something doesn't mean it's true. There is no such thing as absolute certainty, almost any hypothesis is ultimately as viable as any other. I can say "magic makes the world go round, it looks like gravity, but that is just magic tricking us", and there is no way you could prove me wrong.

I hate to go all "society", but I think this is something that isn't appreciated in mainstream education. Science is presented as this almighty truth, when that is not necessarily the case. It's possible, if not scientific, that we were created by the flying spaghetti monster.

Obviously, science, logic and rationale have their place, life would be very difficult to live if you wanted to doubt everything around you all the time. But I also think it's important to take a step back now and then and ask "Is this true?", "Is this real?", "What if what I have been led to believe isn't the case?".

What I'm getting at is that we need to question what is real, what is true, and why; To be open to possibilities, to not necessarily discard things as crazy, certainly not without some understanding of them.
