Who was the natural father of Jesus? Marc Antony or Julius caesar?

Did Cleopatra make a deal with Julius to provide him with a male heir by having a son with Marc Antony who Julius would adopt as the next emperor of the Roman empire? Who was speaking when they said "I will inherit my fathers kingdom?" Was Cleopatra rewarded with the "virgin" position in the emerging Roman theology? Did Octavian become the Christ Jesus? Is the myth of Jesus the eulogy deification of Octavian?Was Julius Caesar the god Jesus spoke of?
