If you want to use Apollo.
I mean the origin of God - whichever.
Whatever comes to your mind is okay. It will be based nonetheless on what you hear, or come to know of.
The fact is, either
it's an idea that just popped into some dudes head, or it's an actual experience people had with a real God?
Do you have any other option? Or is your pick, the former?
If it is, why? What evidence do you have that it is the former? Just a guess right? ...and your guess is as good as the other person. Right?
That's different to a believer. They don't guess. Why not?
They have three sets of evidence - 1. A historical record - the Bible, which they find evidence of it's reliability. 2. Evidence from
artifacts of past civilizations. 3. Evidence from creation.
Each of these three witnesses collaborate.
Of course we can't prove it, nor can anyone disprove it, but it's more reasonable imo, than just guessing based on nothing substantial, and perhaps closing our minds to the later option, which is highly probable, due to perhaps having a biased opinion.
Does this sound reasonable?
