Bugey,
Don't you have a presupposition that plant, animal and human life developed by survival of the fittest? That is, don't you have an evolutionary premise to describe the origin of the earth and the universe? Do you presume
macroevolution?
As for faith/belief of atheism, it entails some of these dimensions articulated in:
Critique arguments for God's existence;
The problem of evil;
Morality and religion;
Miracles;
The motivations of belief, etc
I could discuss other presuppositional beliefs such as
- the nature of God/gods/no god;
- You believe in a material universe that conforms to naturalistic laws and principles;
- This life is the only life we will ever have;
- the power of science and reason and rationality for understanding that overcomes superstition of religion;
- etc.
Do you have any of these presuppositional beliefs?
