Why were kites invented?

They made kites so in thunder storms we can put a key on the end and electricute ourselves. No one really knows Why the kite was invented as we don't know when the first kite was invented. The first written account of a kite is of it being used for lifting a man into the air in Chinca in BC300. However, kites made from leaves are used by several tribes in Indonesia and Polynesia and are used for fishing. The kite is used to hold the fishing line aloft so fish can be caught out to sea. In Taiwan the Ami people also made leaf kites probably their kites were to scare people or for religious reasons as they belive(d?) that spirts inhabited many unusual objects.
