What is real and what isn't? This question may sound redundant at first but if you come to think of it, the only thing that defines what is and is not, is our perception. Perception is what our brain is able to percieve, and how it is interpreted by it. So if this is so, you can see why my question needs to be extended into more thought. Just take this as an example, we may think that ancient cultures were silly by believeing that mythical creatures were real. But think of it this way, what today for us is known as a komodo dragon which is a lizard of great size, that has been studied by scince from top to bottom. So our perception is that this is not a mythical dragon, but rather just a large iguana, while in the early times their perception was feed by ignorance, and religous belief. So, to them this was a creature of mythical powers, and origin.
