Bows are not “incredibly hard to use”. There’s a reason 8 year old cub scouts get to shoot them and manage to hit a target. Weaker draw bows, obviously.

However, for an adult man a 40 pound draw on a compound bow is pretty easy. That’s also the bottom end of draw strength for hunting. In fact, most teens could pull it back. Typical is about a 60 pound draw.

Now aiming takes a bit of practice with a bow or a gun or a rifle. Also, if you’re using a compound bow or a traditional bow.

All of them are not too difficult to learn, but accuracy wise you can learn to be accurate with guns and rifles faster than with bows. Bullets have a much flatter trajectory than slower moving arrows, so if you aim at something you think is 30 yards away, but it’s really just ten yards further out with a bow, you’ll miss. A bullet has almost no change in trajectory over such a small change of distance. Rifles also seem more intuitive to aim.
