Imagine being at the bottom of the ocean and looking up at the waves and currents lighted by the sun.  It would look like the sky.  You could just float up and touch the surface.

Are those clouds or swirling waves of life?

The sky is not the limit.  It’s just a strange space you are curious about.  Be careful.  The rules are different when you’re in the sky and just as unforgiving as any. Walk to a high place and look. Make sure you remember how to get back down.

There are lots of stories about people who traveled through the sky to a faraway place.  Sometimes they became gods, -a strange being; one that no one really knows.
