The only thing in the entire history of the universe that will ever see from behind your eyes is you. You are a unique contribution to the universe.
Whatever time is, it keeps marching on, as evidenced by change. You are here, you effect change. You can not help but to change the world, you can only choose how you do so.
Iron, and all heavier elements, are created in supernovae when stars end their life cycle. The blood in your veins is red because it is suffused with iron. You are literally a child of the universe in every conceivable way. You are made of star stuff.
