Hi doma,
i have not said that things people have faith in are necessarily untrue.
i was commenting on the process of science which is distinct from the process of faith. it confirms or dispatches theories based on evidence.
the theories that survive the effort to disprove them and that fit the facts that are known remain outstanding. as more testing accrues, the more one can feel confident that the theory approximates truth.
science doesn't answer faith-based questions for which there is no evidence. those questions are for believers. if i was a believer in a teapot as the source of creation, i would also be unable to test the theory - the limit of what we can examine is restricted to things inside space and time (and by this i include the possibilities of quantum reality but exclude existence before the big bang).
