Atheist anthropology: from Festivals to International days!

First people are religious and celebrate religious events, then they feel religious events are waste of money and time, then they become agnostic, then they become atheist, then they begin to miss religious festivals as humans, thus to fill up the mental vacuum they start international days: mother day, father day, book day, teacher's day, women's day and on and on and on. In the end atheism is also a cult with its all set of occasions to be celebrated: the cyclic rejection of religion taking you back on the same platform, The Universal irony! 

So wasn't religion very smart to already provide you with festivals to be celebrated as humans on the very first occasion???
