[Serious]Why are you not a believer of the existence of God

[Atheist]

Galileo was persecuted by the Catholic Church for what he taught.

From wikipedia article :


wikipedia article on Galileo Galilei

The Catholic Church in a sense apologized for how it treated Galileo. We all make mistakes so I think the churches have a right to make mistakes too.

Persecuting someone isn't just a simple mistake. Especially when you're such an influential community as the catholic church. These "men of god"...should they not know the truth universe and how its built? If they claim that heliocentrism is false back then, should it not also be false now? Why the sudden change? If they claim to have a book that explains the creation of the earth, and being able to "contact" the creator of earth...why have they been wrong on so many accounts? Thats just one of the things I've been thinking about from time to time.
