We can not prove God exists. Therefore we must look for other "evidence". Its not the evidence thats in question its the conclusion from the evidence.What has tipped the scale for me is as follows.
The tendecy of humans to believe what ever is popular its obvious that the religion you believe in depends on where you are born and raised.
The ability of humans to invent religions.
All societies have had a religion even before
language. "Cave man" pictures on the walls. Humans then paid (offerings) people to interpret the signs of what God wanted them to do. That was their job, to tell us what God wants us to do. Not every religion survived scrutiny. Many societies dissapeared after the 'knowledgeable ones" failed for one reason or
another.
Humans have a strong desire to control the future
as much as possible. Humans want things to be same tomorrow as they are today securing food,shelter, sex was "lucky" gathering and hunting, if you made your peace with your maker it should be easier, if not, he is angry with you. Then you just repeat the above paragraph until hunting and gathering are good again and you can conclude YES! there is a "God".
The tendency of humans of another time and place to assume that others before present time must have thought like we do.
The Christ was actually supposed to return in their time not thousands of years later. It has been predicted ever since that Christ will return in our genration.
People of earlier times "Knew" magic was a reality, some powerful person armed with his "God"(s)could do real harm or curses on you and your family. This was a real fear, thus protecting yourself musthave the most powerful "God" of all.
Their concept of how the universe worked was much
different than ours of present time.
Belief has no limits where as knowledge is limited to pure reason(no reason the sun will not come up in the morning) scientific princples (laws of physics),logic experince and observation. To humans the universe
presents itself as an illusion. Nothing moves unless someone moves it therefore; when the wind blows someone is blowing it. The same for all other natural occuring weather, plagues, famines, floods, earthquakes,etc. Nothing can happen unless someone(thing) makes it happen, is the only possible way for earlier people to understand the universe.
There are many more examples that are obvious to both of us its the conclusion thats the problem. If youstudy the societies that first beiieved in one God it should help understand more human tendecies. Its what we are what humans are that makes God possible.
