William Paley said the world was designed as a watch was designed it was not here just by chance.
Yet someone else can look at the world and see chaos. They would say there is no evidence that God designed the world. Here the world appears cruel and violent. They could argue that there is evidence that says God does not exist.
Nature is not designed but governed by survival of the fittest. In fact the suffering & violence that exists in nature could be evidence that God cannot exist.
Some could see Gods hand at work here. Others would say it is here by natural laws which have no structure.
Some say God did not design the world. The world evolved. This is a very different interpretation.
There is evidence that God exists because I have experienced God for myself. Examples include Miracles visions prayers answered love shown to others during difficult times
Reasons to believe in a God Because my parents or community have brought me up to believe in God.
Reasons to believe because I am afraid of what might happen to me if I do not believe. I might go to hell.
People are evil too If you give God the credit for goodness then you have to give God the credit for evil as well.
The amazing creation of the human body. It is complex and evidence of the existence of God.
The power inside the body to heal. Maybe I should believe in God because the person is so wonderful.
