Proof. Finally.

 From the Twitter account of Jonah Keri:

After centuries of debate we finally we have an answer. Bartolo Colon hitting a home run proves that God exists, and loves us all very much.

 The first home run of Colon's career came at 42 years, 349 days. Colon is the oldest player to hit his first career homer. He unseated Randy Johnson (40 years, 9 days), according to the Elias Sports Bureau.
