Humans can fly with extraneous help of any kind. There was a human powered flight ( pedal powered propeller) and this flight managed to last a few minutes. There are also various gliders which can overcome gravity with the help of designs. However , humans can’t fly without any help , humans don’t have the correct power ratio to flap their arms and fly. Even if we had attached wings we still wouldn’t manage to lift of the ground. So yes , looking back at your question humans can fly with the help of science and technology.
