Being an atheist frees you up to live this life properly, happily, and fully.

I'm pretty sure there is some genetic component towards intelligence.

If we say that religion is a virus, then why isn't science a virus?

Either it is true that a medicine works or it isn't. It cannot be false in the ordinary sense but true in some alternative sense. If a therapy or treatment is anything more than a placebo, properly conducted double-blind trials, statistically analyzed, will eventually bring it through with flying colours. Many candidates for recognition as orthodox medicines fail the test and are summarily dropped. The alternative label should not (though, alas, it does) provide immunity from the same fate.

Although atheism might have been logically tenable before Darwin, Darwin made it possible to be an intellectually fulfilled atheist.

Without gradualness...we are back to a miracle.

Science offers us an explanation of how complexity (the difficult) arose out of simplicity (the easy). The hypothesis of God offers no worthwhile explanation for anything, for it simply postulates what we are trying to explain. It postulates the difficult to explain, and leaves it at that.
