You were responding to a post about Galileo and Copernicus being attacked by the church for talking about 'observed facts'.
Now Galileo and Copernicus advocated heliocentrism and I asked you what 'observed fact' you were talking about and what is the observation that proves it?
If it's a fact, it must have been proved. If it hasn't been proved, it isn't a fact, but a belief.
Wait, you're arguing with -- heliocentrism?
Nah, not really, right?
