Atheist ― When will there be an atheistic style religion with tenets, lessons, guidance in life, morality?

I think you are looking for something oxymoronic. The great thing about being an atheist is that there are no tenets to agree with, no lessons to learn, no guide for proper living. If that is what you want then religion already exists. If you are interested in figuring it out as you go along, making mistakes and learning from them, and ultimately being your own reason for living, then welcome to atheism. Leave your assumptions and expectations at the door.
