Hello! Aristotle VS Galileo--Hmm Who was REALLY correct?

[SittingBull]

I've always heard that Galileo proved Aristotle wrong when the former demonstrated that if 2 unequal masses fall from the same height,the one with the greater mass will arrive at the base at the same time as the lighter mass.
Of course,Aristotle postulated that the heavier mass would arrive at the base BEFORE the lighter mass.
Then who is REALLY correct? Is Aristotle wrong and Galileo correct or is Galileo incorrect and the esteemed philosopher correct?
Hmm
Just wondering.
