Basketball GOAT is Wilt Chamberlain. They changed the rules to make it easier for Jordan, but they changed the rules to make it substantially harder for Wilt.
Wilt is a part of 72 NBA records, 68 of which he still to this day holds by himself. The man retired 40 years ago, and no one has been able to take his records away. That says it all right there to me. 100 points in a single game, averaged 50 ppg for a season, 55 rebounds in one game against Bill Russell, averaged 28 rebounds for a season (half that will lead the league nowadays), and so many more it is difficult to list.
Most of you are too young to have seen this man play. Almost as big as Shaquille, but twice as athletic.
