If 'possibilites' exist to be explored then they existed before we created them, right?
and btw, you didn't define how you comprehend absolute truth. Thanks for adding it...
"If"... They may well not exist until we do envision them. "Possibilities" are ideas, not concretions.
Even if they do have some sort of existence prior to our envisioning them, your conclusion still does not follow -- one can not conclude that therefore there is a God or gods. Mere existence of [fill in the blank] is not sufficient proof for that, unless one is fond of the fallacy of begging the question / circular reasoning.
