en looking at this
I’d say James Brown/Ike Turner created rap. They created the break beats that made funk
Disco DJs made funk hip it the club scene that spread to the ghetto
The ghetto created a merger for both
the DJ pioneers created a hip hop scene. DJ Hollywood provided the rhymes, Melle Mel made it a hot song
During the same (70s) Jamaicans who were influenced by mo town branched off their own thing which created clashing/toasting/ sound systems that also shaped the hip hop culture. But we all know where it originated.
James/Ike who were influenced by the blues.
Beautiful end to the story
