Why is the Sky Blue?

Sky blue for me and you
Why is the sky so blue? 
Does it look the same for you?
Reflection of the sea you say

Which sea I ask you?
The one above or
The one below? 
All the same water, I think

We are but a bubble In between 
As above so below
What did you think it meant?
Standing on our stage of play

No sloshing only still 
Fixed by root, down to the core
Space is but water, not a void
We must swim to get about

We, are not the only dome, you see
More around with in the sea
Crystal structure of the dome
Gives us the colour Blue, HOME
