I'm an Atheist.
It seems like a collection of subjective experiences.
That's because it is. And that's what makes it religion.
How do you or anyone else know that it has anything to do with God? How would you reference a God in those cases?
Most religious viewpoints, regardless of what the people exposing you will claim, are not based on scripture. Nor does basing it on scripture help you any; a casual glance at history should convince you that there are a whole range of (often contradictory) positions supportable by biblical reference, for example.
