"Thanks to" something is just a figure of speech. I meant "due to" it.

You really think atheism is foolish in the twenty-first century? That's silly.

There's plenty of mystery in something that's inherently different from us. Indeed, that's the very essence of a mystery. The scientific picture of most of the universe is that it's lifeless, and lifelessness is alien to life. That's why death is so scary.

I'm not denying the source of truth, beauty, and goodness. They come from us, and specifically from our minds, and mental explanations aren't so easily reduced to basic material explanations.

You don't need theism, then, to have foundational mysteries that make up our existential condition. On the contrary, theism trivializes the great mystery by personifying the unknowable.
