God, as Experienced, and as Metaphysical Speculation "If you doubt that truth for humans is socially constructed, then answer me this (I would genuinely like an answer if you have one): If truth for people is not socially constructed, then why are religious and political beliefs correlated to geography?"
Different societies have different languages to express spiritual matters but the differences are often secondary and not a measure of 'truth'. For example Confucianism, Buddhism, Taoism, Christianity and Judaism have much in common.
"How did people believe that they experienced God? I have read that the word “unconscious” was used for the first time in Germany in the 18th century. If people didn’t even have a word for the thing, it’s likely that they didn’t have a concept of it either. But if there is no unconscious to make your thoughts and feelings pop into your head, where do these things come from? Ancient people believed that they came from polytheistic gods (Ares = anger, Aphrodite = lust …) and demons and angels. They believed in their gods because they really did experience them. We just do not today believe in their interpretations of their experiences."
You seem to be saying that 'the unconscious' explains things. But that is a tautology. What is the unconscious? To answer that you have to know what the mind is. It seems to me that the unconscious is 'knowledge beyond language'. That is, knowledge that enters our minds through awareness but is not yet translated into conscious language.
"It seems logical that there is a limit to what God can add to himself personally, since he is infinity, and anything added to infinity is still infinity. So, God does not add to himself directly, but creates an infinity (or at least a very large number) of finite things."
Not necessarily. You can have an infinity of odd numbers 1, 3, 5, 7,...
And to that you can add something different; even numbers 2, 4, 6,...
