A more thorough explanation:

Irresistible superhuman cause refers to an overwhelming and unpreventable event caused exclusively by natural forces, such as an earthquake, flood, or tornado. This definition has been broadened to include all natural phenomena that are exceptional, inevitable, and irresistible, and the effects of which could not be prevented or avoided by the exercise of due care or foresight.

For example, if a hurricane causes a tree to fall on a person's car, it would be considered an act of God. The person could not have prevented the tree from falling on their car, even if they had taken all necessary precautions.

Another example would be if a sudden earthquake caused a building to collapse, resulting in injuries or deaths. This would also be considered an act of God because the earthquake was an overwhelming and unpreventable event caused exclusively by natural forces.

In both examples, the events were caused by natural forces that were beyond human control, and the effects could not have been prevented or avoided by the exercise of due care or foresight.
