You have been focusing on the literal words in the Old Testament, which was written by men, and have used some of those words to try to prove that God does not exist. But God is not words, spirit is not stories about bears, religious feeling is much more than what was written in a book thousands of years ago.
Mystics and metaphysicists use feeling and thought and philoophy to contemplate the nature of reality and God and huge questions such as truth, justice, evil, good, ethics and the creation of the universe.
Just because they don't use science does not mean that they cannot perceive the truth, because the truth of the spirit is beyond science and lies in the realm of thought and philosophy.
