"The product of consciousness" is also all psychopathology, all the crank and dementia, including religions, that people are able to come up with. This argument holds even if we're not (yet) able to pinpoint exactly what is consciousness (and we know that it's the product of highly developed organic matter of the brain). To say that science justifies belief/creation in any form is crying stupidity. Science justifies a rational, scientific view of the world - materialist monism. In this context, there is no room for any religion/superstition/spirituality..
