No one can take anything away from Michael Jordan for his success on the court, but before you start flapping your gums, you need to read Wilt Chamberlains story. Go to Wikipedia:

Even if you feel like skipping his early career, the stats on his Rookie season are astounding.

"In his first NBA season, Chamberlain averaged 37.6 points and 27 rebounds, convincingly breaking the previous regular-season records. He needed only 56 games to score 2,102, which broke the all-time regular season scoring record of Bob Pettit, who needed 72 games to score 2,101 points.[39] Chamberlain was named NBA MVP and Rookie of the Year that season, a feat matched only by fellow Hall-of-Famer Wes Unseld in the 1968–69 NBA season, and broke eight NBA records."

He broke 8 NBA records in his ROOKIE season. Read the whole story. then tell me about "who's the greatest."

And " Chamberlain's 4,029 regular-season points made him the only player to break the 4,000-point barrier;[2] the only other player to break the 3,000-point barrier is Michael Jordan, with 3,041 points in the 1986–87 NBA season."
