According to Karl Popper, a hypothesis is scientific if it can be observationally falsified, not, if it can be verified. One instance not in accordance with a supposed law refutes the law, but many instances in conformity with the law still do not prove it. Accepting this falsification test, we may remark that the idea of the divine existence either could, or could not, be falsified by a conceivable way of observation. If it could not, then science in no position to test theism. Please comment.
