Science CAN prove that the human species is older than 6000 years and that we did not spring from a single human couple.
Science CAN prove that there was no global flood about 4300 years ago, with all the attendant migratory nonsense that that implies.
Science CAN prove that evolution is true.
Science CAN prove that a man cannot defy physics to walk on water - or defy mathematics with loaves & fishes - or defy chemistry to turn water into wine - or defy biology and raise the dead.
Science can prove a lot of things - important things, but it can't prove or disprove everything. It cannot disprove the existence of your favourite deity, but then, why should it even try? There are much more important problems for science to spend it's time, resources and effort trying to find an answer to.
Problems your god won't lift a finger to address.
