The proof is that the IDF dropped 30,000 bombs on Gaza, which destroyed over 270,000 homes.
Yet, despite the deliberate targeting of homes housing children, they filled an estimated 30,000 people civilians and, according to the dubious numbers reported by the Hamas minister of health, zero combatants.
Even accepting the casualty figures at face value, that would make 1a whole of one civilian per bomb and one-ninth of a civilian per home.
If IDF is targeting civilians, their success rate is really below par.
