No worries, the ‘machine gun’ is about out of bullets -
In my long, long experience as both a scientist and an active skeptic, I have seen people believe in a lot of seriously, um, odd stuff. In many cases, it doesn’t matter how overwhelmingly the evidence is against them, or how even simple logic will unravel their tangled theories. They cling to these beliefs like a drowning man clings to a life preserver.
And even with all this, I have to scratch my head over Geocentrists.
These are people who believe that the Earth is fixed in space, unmoving and unmovable, and the Universe literally revolves around it. Without exception, in my experience, these followers of Geocentrism believe in it due to a literal interpretation of the Bible. Finding passages in the Bible to support this belief isn’t hard; Genesis is loaded with them.
However, like young-Earth creationism, the problem here is in that “literal” part*. If you take the Bible to be true word for word, then you have to deny a vast amount of reality, and almost everything we’ve learned about the Universe since the Bible was written.
