Rarusu this is for you.
An attempt to disprove God.
If you look at dictionary.com it defines God as the one Supreme Being, the creator and ruler of the universe. But that is where it stops being specific.
Billions of people all around the world define their deity or deities differently. It doesn't just differ between Religion, it also differs between denominations, the country and culture you're in and also personal belief.
So it isn't Holy scripture that defines who or what God is. But rather the followers. There are people out in the world who will tell you what a God or Gods want but haven't even picked up the holy book their trying to follow.
So, therefore if I take a creationist, who follows the Bible to a literal sense. That man believes in the young Earth, the global flood, Adam and eve etc and you taught him about Religion. And I don't mean from a text book I mean from ACTUAL EVOLUTIONARY SCIENTISTS who have the latest and greatest sources of information anywhere in the world. And you spent 1 whole session teaching him about Evolution, the Big bang etc. Then that man thinks "what I believe is wrong, the Bible doesn't teach this. I cannot ignore the evidence. So that must mean, God and the Bible are all a lie"
Have I now disproven Gods existence? Of course not. But if we use the method of "faith" and apply it on a global scale. Does that not mean that we can't disprove any god or gods from dead Religion even though Theists and Atheists agree they don't exist?
There are millions of God, Goddesses, demons, angels, messiahs, prophets going from the largest organised Religion right down to the smallest cult, and we can't disprove any of them.
It's NEVER about how strong the Religion is, it's NEVER about what it stands for or what it does. It's ALWAYS about the how the followers interpret that God or Gods. and it is THAT self interpretation that defines a Gods existence and nothing else.
So all you need to do is kill the Religion, and the God will die with it. Is it concerning that Religious percentages have been on the decrease? If it wasn't it is now lol
