Yes. Belief is grounded in nothing - hence it is belief. One could believe in moon Nazis, or Bigfoot, or god - without a shred of evidence for any of them. Knowledge is based upon rationale and testable hypotheses.
Belief that you exist, belief that free will exists, belief that others have consciousness, belief in human rights.
