The earth is all that we really know.

It's big and round, and extensive. 

Never will one person see everything in it. Every nook and every crany... It's impossible.

No one will touch each rock, each stone, or grain of sand. Which lay so small against your fingertips when you touch them.

It seems un-important. So easy to step on and ignore. To realize it doesn't exist.

Yet, if you look upwards into the sky, into space. And fly forever outwards, you'll see that earth is really just a grain of sand. Floating in an existence of millions of others, soon to be out of sight. So quick to disappear.

And you, yourself, are a piece within that tiny blue grain. Yet, you exist. You breath, think, and move. 

Who's to say that there are only mysteries in the cosmos. Why not here? On a blade of grass, or water dropplet, or even a flower?

Just remember that things are just the same big as they are small.

And Horton, well, he really did hear a Who.
