Where was wrestling discovered?

Answer 1

i have given a long and detailed answer to the above link, and it is a very similar answer to one i would give this

but trust me, that is a very very long answer and youd have to be really really interested in the history of Wrestling to read it all, so the short version is:

Japan invented a martial art similar to wrestling called Shuai Jiao four thousand years ago, Egypt invented amateur wrestling (Olympics) circa 2300 BC, professional wrestling (WWE and TNA) was invented in the 1800s and was performed mainly at carnivals during that time.
