Science can actually provide no facts based on the way the scientific method works. All hypothesis' are "proven" through tests that do lead us to a truth but can never 100% guarantee that it is a fact, hence why theories keep evolving over time as new evidence "disproves" old theories. It is all inductive reasoning which can never 100% prove anything. Science is not a sham because of it, quite the contrary... but most people "trust the science" and don't actually know what science can and cannot do.
