The most important reason anyone is an atheist

[Neo-Scholastic]

Not any more than your own. I find that positing the existence of transcendent principles produces a more consistent philosophy that explains reality better than the alternates.

But it doesn't provide any evidence. Explanation without evidence is hypothesis.

When you have evidence of the existence of a god, then I will be able to take your hypothesis seriously.

And exactly what evidence do you have that physical reduction is true, especially since it is so strongly counterintuitive?
