Try telling me that with a straight face when I can shoot fireballs out of my hand, walk on water, and raise the dead
The problem with those elements is that because they are fantastical in nature, they don't adhere to physical laws or historical precedents. Although, I'm sure some of the first people who got their hands on gunpowder made people think they could shoot fireballs, and for countless centuries dozens of religions have believed in resurrection of the dead.
Anyways...since bows, arrows, swords, armor etc HAVE been used in real, human, life, we know what to expect from those items. For them to act outside of what we know to be true would seem obviously wrong, like if someone walked into the room...on the ceiling.
