One of the curious things about atheists is that they seem to take pride in saying that what they believe today may very well be proven false tomorrow. It makes them practically giddy to live in a perpetual state of doubt. And in fact they think that everyone else should live in like manner.
But why would anyone live by and base your eternity on something you think is probably false?
Why not instead lean toward those conclusions that bear resemblance to reality?
I guess to some people, anything is better than acknowledging one's Creator.
