I can relate. I was raised a Christian myself, but as I got older, let's just say that my idea of 'God' evolved. I just think it's interesting because Catholicism seems to have a considerable tradition on the supernatural (demonic possession/exorcism, stigmata, Marian apparitions etc.), but I guess you don't buy any of that. FWIW Christianity runs the gamut from heavy emphasis on the supernatural (prophetic revelations, Holy Spirit manifestations etc.) to the sobering, defensive stand against any sensationalism. Somewhere in there may be the true supernatural among the frauds.I have not and I do not 'believe' in anything that is not scientifically observable. There are many, many things that have been proven to be real that I have little to no knowledge of and I do not need the billions upon billions of 'unprovable possibilities' diluting reality any further.
Give me proof and I'll adjust my world view accordingly, as I must. Such is the fate of one who subscribes to science.
If you open your mind too much, your brain will fall out.
EDIT: I say this having been raised catholic and having spent most of my teen years 'studying' demonology and myriad religions, as an edgy teen goth is supposed to. Even tried my hand at Wiccanism for a year of so. I truly believed for a while but eventually the lack of observable truth just killed it. That, and the cases of borderline insanity such beliefs wreaked on some of my acqaintances made me realize blind faith is dangerous as hell.
