loving you is all i know lyrics

I don't understand how the sun keeps shining
And I don't understand why the seasons change
And I don't have a clue what makes the river flow
Loving you is all I know

I can't tell you why stars come out in the evening
And I can't tell you where they go when they're gone
And I don't have a clue what makes a flower grow
Loving you is all I know

I don't know how the world keeps on spinning around
I don't know why the sky don't come falling down
I just know that I would die without your touch
I don't know what a time just to reach the shore
Just know that I'll need you for forever more
Knowing that, I guess I know it now

I can't really say if there is a heaven
But I feel like it's here when I feel you near me, baby
If angels are real, they must know how I feel
?Cause loving you is all I know
