A person who is a vegetable might not have any goal to be happy. But if you have any kind of a goal, you have religion according to some of the definitions of what religion is.
May you define your notion of religion then? Because maybe we disagree on the definition and that's all. And as it is a very complex notion, it might be possible.
Don't tell me that an atheist is outside the universe. If an atheist has purpose and is in the universe at the same time, then the universe has purpose. Nobody knows whether or not the universe is a thinking entity that has purpose of itself. But the fact that people in the universe have self-designed purpose, makes it impossible for the universe to NOT have purpose.
And that's the main difference between atheist and religious: atheists have their own goals, religious follow a higher goal/guideline, which is god.
And what you're saying is wrong, I understand what you're trying to explain but that's not true
There is more than 7 billion people. Each of them have their own goals. So what is the purpose of the universe then? The average one? The most common one?
If there was only one human then I would understand your point, from his point of view his goals would be the only one existing in the universe. But that's not the case.
