Why light is the fastest thing in the universe

What is there in light that it is so fast, let’s find it out; Light travels 299792458 meters per sec we can’t travel that fast. Why can’t we go that fast? As we increase our speed we will need more and more energy because we got mass and light doesn’t have any mass. So if we try to travel that fast we will need infinite numbers of energy but as light didn’t got any mass so it can go that fast. That is what light is the fastest in our universe.
