How ever even if Einstein was a theist, it does not prove anything., unsure:
I am not trying to, by invoking Einstein, to have authority, he just resonates with me in his original expressions (he lived in my home town for a long time).
He was not a theist, but a deist. He had a disastrous family life and rejected a personal, intervening god. did not believe in an afterlife : "ach was"
I agree with you, that it is confusing to listen to all the arguments or sort out what supposedly inspired books or interpretation thereof give by way of insights into "god".
Research into creation itself should give a picture of the creator, or absence of.
Listening to the results of the top researchers, theorists would give us an inkling.
" go not beyond the things written created" , my credo.
