The atoms that make up every single part of our brains and bodies were created in the centres of stars billions of years ago. Each person may well be a unique configuration of those atoms, but these building blocks are older than the Earth itself.
As has been said, we are stardust.
But we are conscious stardust. Unlike the chair we are sitting on, we are aware of our surroundings and are capable of thinking about, reflecting upon and learning about the universe in which we exist.
We are the consciousness of the universe. We are the universe discovering itself.
We are not separate from it. We are it.
