Well, you are quoting a lot of Theravada scripture, a school whose teachings are carefully phrased to not encourage any eternalist tendencies. Here's a typical one:I don't know, I actually just got into buddhist scripture. My favorite texts of the teaching before that was The Gospel of Thomas.

But other schools have different takes.
