Well there would be a lot of benefits if it were real, but all the nice possibilities thought out by the bible writers were unfortunately fictional mythology.
The ancients asked for help to their specific worshiped gods they didn't have the knowledge of the world in which we lived so they had no others choice.
In other words they created their gods and also created ideas for help from those gods. ie sickness, war and strife and death.
In many ways the humans who lived in that era were much like the people living today
