God in its all form are part of every human culture. In some they have no form, in some they imagined in human form only. If one tries to understand why humans have faith in god it is possibly because of forces of nature. It is also evident from god of ancient civilisation. For example many gods either are representing a natural force or they are worshipped in their natural form, best example one can think of the SUN god. Sun god has been an important part of every ancient civilisation. Other examples include god of rain, Mother Earth, god of water, god of fire and many more. This also seems a valid very  right to consider forces of nature to be God as these forces are only responsible for creation and care of life on the planet.
