The reason heating milk kills bacteria is because of enzymes. Enzymes are molecules inside bacteria that catalyze all the biological and chemical reactions that the bacteria need to survive.
If you heat the milk then the temperature inside the bacteria also increases. This "denatures" the enzymes. What this means is that because of the increased heat energy the molecules inside the enzymes start to vibrate more violently. they break the intra-molecular bonds and the structure of the enzyme collapses making it useless.
If the enzymes don't work then they can't preform the functions that the bacteria needs to keep it alive, so the bacteria dies

Who invented a method to sterilize?
Louis Pasteur in 1861. He saved the milk and beer industries by suggesting that people lightly heat the liquid is a sealed container to kill the germs. His germ theory was what helped him figure out that it was germs that made food go bad, not bad food that made germs, which in turn was key to his pasteurisation idea.
