Father of Physics is Aristotle. He made physics a separate discipline. Modern Physics developed only out of critical inquiry of the Aristotelian ideas.
It is pointless to say that Aristotle was wrong and Galileo was right. Galileo received all his raw materials for the critical inquiry from Aristotle. Aristotle’s ideas were wrong. But in case there were no ideas on Physics at all then there would have been no Galileo or Newton as well.
