Before the age of four I have no coherent memories so I suppose it is possible I held such a belief.
However, I remember myself at a Catholic Sunday school hiding out in the back of the bus with a couple other kids avoiding the days end mass and having the revelation that the grown ups actually believed there was a real god person and wondering why they held such a belief.
Until then I assumed god was indeed like the Easter bunny for grown ups.I thought it was a game.
I must have been around 4-5 years old.
Other than that Sunday school I didn`t have much religious influence in my life as my family were Easter Catholics who went to mass only for such special events.
Have you ever looked for evidence to support the idea? Just curious.
Extensively.
I`ve studied mysticism, Christianity, Judaism, Islam, and the veracity of other paranormal phenomenon.
I`ve found nothing to convince me.
