why?

I remember when I was at the beach
     Little hands
And tiny feet
     Shovel
In the sand
     Before it was placed
In my hand
    The steaming sun
Blazing on us below
     At that point
I couldn't wait for it to snow
     Slathered with sun block
Is the nastiest feeling
     I always asked
" How does this block the sun?"
     And
Always wondering
     Why is the sky blue?
And thinking why is there only one sun and not two?
     I guess I couldn't say if I knew any of the answers
There is more than one answer to chose
     So I guess I'll spend my days in a wonder
Always thinking about these questions
     Every time I think it will put me in that wondering gaze
Try to really think about it
     Is always a challenge these days
