I do not believe but I did at one time, and this is what I believed:
How powerful is she/he/it First off, it is genderless, or gender may not even apply. It’s not human or human-appearing. It was a nebulous entity which may or may not be recognizable to us if we saw it.
what is she/he/it made of Unknown.
what can/can’t she/he/it do The god I thought I believed in was bound within the universe - it did not create the universe, it was part of it, and would end when the universe ended.
where does she/he/it reside Unknown. I did not believe that god fervently watched over the earth and the people on it, heard prayers, etc. I believed that God sort of set life in motion many years ago and for the most part sat back to watch in general how things were proceeding, with occasional intervention to push things along. I also believed it was likely God was doing the same on many different worlds in parallel.
At one time I believed that the “spark” of consciousness within each of us was a part of god, and that whatever we did in our lives changed god overall, because when we died that spark returned to the source and carried with it some of the “development” it went through within us. No heaven or hell or purgatory or limbo, just a flow of energy so to speak.
I think that god would have been/was highly disappointed in most organized religions, such as Judaism, Christianity, Islam, etc. That god would have wanted a sort of “benevolent natural philosophy” to take over - one where education, learning, science, etc. would help us become a better race, mutually beneficial for all.
That’s what I believed; I haven’t believed anything like that for a while. I now believe in a cold, empty, universe which will die a heat death forever and ever meaning that everything we are and do right now is meaningless and pointless and stupid. I don’t like writing about it and the only reason I’m doing so here is…I don’t know.
I’ve answered the question the best I know how.
