I believe that in early Earth when the volcanoes were erupting that some water collected and it rained and stormed and when lightning hit water dropplets in created organic compounds which under pressed condensed down to bacteria which feasted on the other organic compounds and over 4.6 billion years we are where we are....Now see I know how to use big words...
I believe plenty of thing but I don't believe there is any higher power control anyone other then our own conscience.
Basically, religions have moral values with them as well and bushido is a code of ethics. I combine the morals and ethics that I agree with from each religion and code of ethics to get a complext system of ethics and morals. :3
