I do not believe in any god, deity, higher power, nothing like that.
It's just the way I was brought up, liberally. I was never christened (as seems to be the tradition) because my Mother always maintained that if I wanted to believe in God and get baptised, then I could when I'm old enough to decide for myself.
My Father's side of the family are predominantly Roman Catholic, my Mum's side were never religious either.
Ultimately, they never dissuaded, discouraged or encouraged any such views upon me, they let me decide for myself. Which I think is the best way to go about it.
