There are many reasons one of them being that guns make you feel safe. Usually most thieves will run at first sight of a gun, you won't even have to shoot it and it can save your life to have one in case of real emergency. There are many videos on youtube that show guns saving lives.
Shooting is a fun recreational activity. You should go to a range sometime and see for yourself.
Another is that guns are pretty in a way. Some people find beauty in swords and knives, others in pistols and rifles
