The two main objectives of grounding are to

Grounding creates a stable reference to earth and a low-impedance path for fault current. The two main objectives are to limit the voltage that exposed conductive parts can reach relative to earth, so touch voltages stay at a safe level, and to provide a low-resistance route for any fault current so protective devices can detect the fault and trip quickly. When everything is bonded to earth, normal operation keeps equipment at or near earth potential, reducing the shock risk. If a fault occurs, the grounded path carries the fault current back to the source, creating enough current to trip fuses or breakers and clear the fault, protecting people and equipment.
