How is it that a bullet that is 12.7 mm in diameter can kill somebody with so much more bodily damage than a 20mm rebar rod that is impaled through the body? I see stories of people surviving impalement all the time, but a shot with a .50 cal to the same area almost always results in instant death. Shouldnt the bullet just go through its target because it travels so fast?

Because air has mass and the slug momentum P=MV. It’s about the total energy transferred. The kinetic energy has to go somewhere.
