I admire your loyalty towards MJ but your post has some inaccuracies.
For example:
‘Thriller’ was not the biggest selling album of all time before the release of the ‘Thriller’ video.
It did become after the release of that video, when it sold even more copies that the ‘Saturday Night Fever’ album & overtook it in 1984.
“
… In February 1984, it [‘Thriller’] would overtake the Bee Gees’ Saturday Night Fever and become the biggest selling album of all time…” (Matt Richards & Mark Langthorne, 83 Minutes book)
Even if John Landis claims the opposite, apparently he is wrong on that because exact sales figures (between these two albums from that period) disprove him, too.
A bass line which MJ lifted from ‘I Can't Go For That (No Can Do)', a song already released a year before by the Hall & Oates duo.
‘Human Nature’ is a very good song performed on stage by him, but note that he was not involved at all in the song’s making (apart from the vocals).
MJ was not really the nucleus of those particular things.
Generally, MJ borrowed a lot of things/ideas from other artists which certainly does not make him the nucleus of many things concerning his art.
MJ was also helped a lot during his career (including the ‘Thriller’ era) by other very important people.
There is a reason why Mike Smallcombe emphatically used the verb ‘make’ in his book’s title about MJ (‘Making Michael’
