Nope. never been agnostic. Theist through and through...but refusing to be tied down to doctrine.
As for before I was born, cantleave...well...there is a school of metaphysical thought that strongly supports pre-existence, and I quite like that...not saying I believe in it, but I do like it, and I don't like to preclude the possibility.
So, if the premise is "we are all agnostic," I am reserving the right to still be the exception that proves the rule.
Except that I refute both premise and rule.
Just to be awkward!
