Classical Gauge Theory Genesis

In the beginning God created the heaven and the earth.

God designed the matter Hamiltonian H(p,x).

And the earth was without form, and void; and darkness was upon the face of the deep. And the spirit of God moved upon the face of the waters.

Something seemed missing, God pondered.

And God said, Let there be light.      

 Let p → p - qA

And there was light.
