UU versus Quakerism: what is the essential difference? And which one is better for someone who has a scientific bent of mind? I am sleepless thinking about this question.

UU versus Quakerism: what is the essential difference?

It seems like Quakers believe in the six principles, most of which most people would be on board with. That seems to be the sum total of their beliefs.

With UU people, it seems like something like that is not there because people can believe what they freely choose to believe in.

My second question is: which one is better for someone who has a scientific bent of mind? I simply cannot bring myself to believe in anything supernatural. I cannot lie about this. I just know, for instance, that Jesus never walked on water. And so, any religion X that tells me that this is a part of what I need to believe to be part of religion X I cannot be a part of.
