Testable, indeed, but always from an observation standpoint to which can be referenced to reproduce these tests (=consistency). Since an absolute, grand unifying, written-in-stone standpoint does not exist -ie human observation is limited by its senses- I will gladly accept (a tiny bit) of herd behaviour around a mystical energy pool that linguistically is referred to as God.
The bloody rooted "Christendom" led by one (male) pope, the tribal herd behaviour of Muslim (tribalism being exactly what the Prophet tried to fight by unifying under Allah (= Arab for God)), the predecessor Bhudism with its way to enlightenment and Hinduism before Bhudism with Brahma, Vishnu and Shiva as a trimurti around the energy pool and the mythical tales even before that should instigate a critical stance to what happens around you (=observation).
Religion so wants to let you believe in its holy guiding lines to live by, it should put a healthy bloke on his "qui vive" (a gallicism in Flemish as a way of referring to extreme alert behaviour).
This "qui vive" is a great departure point for science.
