Are we like fish in a sea of particles?

We are assembled by the particles of star dust also known as carbon whereas magnetic energy from the sun and other stars in a infinite universe sequences those particles into a particular order, thus is there choice or even anything non calculateable by definition , if there is a math value to fluctuating energy as decipherable via its previous state of fluctuation, is time repetitional in that life and death have already happened via the thought as the same energy as physicality including rebirth?
