Atheism needs something, currently it has no moorings of which it can justify itself.
All Atheism has for a fundamental building block is the stamen “Their is no God because we said so.”
Denial is the only precept. Atheism cannot explain a single thing in the physical world (that was the point of the listed miracles in the article, physics fails entirely to justify a lack of God’s existence) nor the metaphysical as all the suppositions have no basis, only assertions.
Seriously, attempt to create a justification for an individualistic moral sociality outside of a Creator. It continues to baffle all who have tried.
Simple experiment, explain why I should not take advantage of every one I see if I can gain personally from it, regardless of who it harms. If I can get away with it why should I not? Not talking a forced legal aspect, literally disusing the core moral justification for anyone to do “good.”
In a chaotic universe of randomness there is no “good” and no rationally justified reason for a person to choose another’s “good” over their own self interests.
No, atheists say "There is no God because the more we learn the more we find out that there isn't any organized intelligence in the universe except us." And that doesn't cause them any anxiety whatsoever.
