Both religion and science are theories. Both explain how we and the entire universe came into being. Believing in scientific theories is similar to believing in a religion. Religion and science remain separate and cover their own area, but when put together you get a “theory of everything”. When put together you have practical theories and spiritual theories. Religion and science definitely complement each other because science is unable to prove that there is no higher power, spiritual being and religion is there to fill what science has not been able to do.
