“Is all that we see or seem, but a dream within a dream?”
-Edgar Allan Poe

Think of the vast, incomprehensible amount of space that is the earth.
Think of all the continents you’ll never go to; the countries you’ll never see; the cities you’ll never experience.
The people you’ll never meet and the houses you’ll never enter.
Sure, you’ll see pictures and videos.
But how do we know; how can we be sure, that anything is there?
Behind that facade could be a living room with pictures and memories frozen in time. Or, an perpetual state of nothingness, only changed by your existence.
Yes, you.
The world is yours.
The world is a figment of your imagination.
A computer simulation.
The dream of a slumbering dragon.
Nothing exists until you make it exist.
And with every birth is a death.
Can we ever know the whole earth?
Why not? It is your world.
You did create it.
But limitations exist to the amount you can know for you are not omnipotent.
Each opened door closes another, leaving us running from door to door out of breath, trying out best to make everything exist at once.
But we cannot take in all that is the earth at once, so we must open each door, one by one.
