Step-by-step explanation:
In principle, it is very difficult to establish the existence of the supernatural. Miracles, which are events that violate the laws of nature, can be seen as potential evidence for the existence of a supernatural being, such as a single Supreme Being. However, it is challenging to verify and establish the occurrence of miracles with clear and indisputable evidence. Additionally, there are often alternative explanations for such events, which makes it hard to conclude that they are the work of a supernatural being.
