Religion was at the center of everything when human knowledge was very limited, and religious claims could not be proved or disproved. While knowledge progresses, religion is still in the business of making claims about non-falsifiable things, but the amount of things non-falsifiable has been dramatically reduced; they have been pushed out of the center to the margin, where they can still keep on making non-falsifiable claims. They have been in a slippery slope since immemorial times: once they are caught red-handed, they adapt the message, even accepting newly established facts as an expression of their god of choice. So yes, religion can not be disproved, since once you find out a fact which could disprove it, they basically say "you did not understand what we meant, we meant exactly this, and this how our god is responsible for this newly found fact".
