Lyrics

93 million   from the sun
People get ready, get ready
'Cause here it   it's a light
A beautiful  
Over the   in to your eyes

Oh, my, my
How beautiful
Oh my beautiful  
She told me

Son in life you're   go far
If you do it right
You'll love where you are

Just know that wherever you go
You can always come home

240 thousand miles from the  
You've come a long   to belong here
To share this   of the night
A   night
Over the horizon is another   sky

Oh, my, my
How beautiful
Oh my irrefutable father
He told me

Son sometimes it may   dark
But the   of the light is a necessary part

Just know, that you're never alone
You can always come back home
Oh oh oh
Oh oh oh
You can always come back

Every road is a   slope
There is always a hand that you can   on to
Looking deeper   the telescope
You can see that your home's   of you

Just know, that wherever you go
No you're never alone
You will always get back home

Oh oh oh
Oh oh oh
Oh oh

Oh oh oh
Oh oh oh
Oh oh

93 million miles from the sun
People get ready, get ready
'Cause here it comes it's a light
A beautiful light
Over the horizon in to our eyes
