I am of the opinion that the idea of god stems from the need to feel grateful for existence but nowhere/no-one specific to point this gratitude towards. Are there any studies out there which validate or refute this argument?
Man created god to explain the unknown and discovered a means of controlling other men.
Man grew up a little and created a framework that can explain the unknown without gods, it is called science, and one day it will render all gods into the myths they really are.
God(s) originated out of a need to control fear through stories, myths etc. A way to define the unknowable nature of a cruel capricious world. From there it evolved into a way to to define a cultures place in the world and carry on stories and information to the next generations and glue together larger and larger groups. I do not think it had much to do with being grateful in the beginning more it was about trying to understand the world with a distinct lack of reliable information.
Other than my previous post of my explination of the word God, see wikipedia as a starting point for an interesting topic to consider further. See wikipedia: "evolutionary origin of religion " and "Imaginary friend". I understand wikipedia is not considered a verifiable source but it can be a place to view ideals for further resesrch.
God defined as a word of open definition and usage, in that any person could give any usage or define it in any way, whether logical, provable, real, surreal or not.
There are some things labeled by this word that have more popularity than others. There are groups of people that give a certain definition to this word that the agree on and follow for that group. There are those that would say there is nothing in existence that this word would properly label. There are those that do not have evidence for a reason to label anything with this word. There are those that could never know what to label with this word. There are those that would label some immediately unexplainable occurrences with this word. Some may of had some occurrence that there is no current scientific word or other explination, so a reason to use this word.
A very uncommon word for how it is used comes from Germanic origin of meaning to call or invoke and now in fact exist as a word in English spelt with the letters G, O, and D.
It’s difficult (impossible?) to have an idea of anything one has never perceived, or the parts of which one has never perceived (like a flying horse). Freud suggests that the idea of God comes from our idea of a father whose imperfections have all been imagined away. That seems probably right to me. But why should believe that there exists such a being? I think Xoviat’s suggestion that we feel a need for someone to thank for our existence—and any other undeserved bounty—has merit.
