Do we really need balls?

Of the sporting variety, naturally. Having finished with the (English) footie, we are now into Wimbledon, and then the Olympics, which although not all about balls is sure to feature quite a few. What would sporty people do if balls had never been invented? Run about and jump over things, no doubt. Ever higher and faster.

Once upon a time, someone ( who?) made a small round thing and either threw it or kicked it to someone else. Why?

I do not like balls. If I see one coming at me, there's a part of my brain that says: Missile! Avoid and/or duck. Both, if possible. I cannot catch a ball or hit one ( many have hit me). I do not enjoy watching other people throwing and hitting and kicking. Is there something wrong with me? Does one have to enjoy balls and ball games to be fully human? And am I alone in being totally bewildered by the rules of cricket, rugby scrums and the offside rule?

Last of all, is there anyone else out there who can live without balls? If so, please let me know. I think I'm in for a rather lonely summer...
