A.S.K. your way to proof.

Why should I care what Voltaire's opinions on the future were or what happened to his house. There was no way to determine the percentage of atheists around the world in his day, where did you get 3.5% from?

because he was king atheist and started the movement and grandfather the same BS arguments you guys still use. IE if he was wrong about his prediction based on information and an understanding of God you guys still follow then he was wrong about his base beliefs IE you in turn are wrong where your beliefs cross.. Do you people not even understand your origins and shared beliefs?

his house being used  is just insult to his proud proclamation.

There's a big difference between 'noted' and 'king'. Atheism isn't a movement (notwithstanding Conservapedia), although atheists can be part of a movement. There are a lot of atheists in the Skeptical Movement if that's what you're thinking of.

Voltaire not an atheist, noted or otherwise, he was a deist, I think of more note would be Lucilio Vanini, freethinking pantheist executed in 1619 for his supposed atheism by having his tongue cut out and strangling, followed by burning his body. Atheists are more likely to quote Epicurus (341-270 BC), paraphrasing his famous trilemma, than Voltaire.

And you didn't address where you pulled your estimate of 3.5% of the world's population being atheist in the 1700s. I don't know how anyone would have arrived at that number, and it sounds way too high. Are you sure it wasn't just France?

His house being used to store Bibles is typical low-class petty vengeance on the part of the Christians involved. Today it is a museum.
