Belief is not alway irrational. A large number of
biologists believe in
evolution. A large number of geologists believe that the earth is x
billion years old. A large percentage of the Western world believes that
the earth orbits the sun. Are those beliefs irrational, simply because
someone believes them? Is something instantly irrational *just because
someone believes it*?
Evolution can be backed up with evidence. That the earth is X billion
years old can be backed up by evidence. That the earth orbits the sun
can be backed up by evidence. Creationism can't be backed up by
evidence, it is un-verifiable and un-falsifiable. Belief itself is not
irrational. Belief that cannot be backed up can be.
