Why are humans believe in superior being is because our mind are program to give sens of what is around us. But the problem is that our mind is not strong enough to understand everything so he create some sort of God to give a sens to unanswered questions like ''why do we live'' or ''what created the universe?''.
A proof that God is pure fiction is there are things that doesn't stand. As thelogy describe God, some things are in contradictions. For exemple, theology said that God is almighty strong and infinitly love. He has the ability to do anything and love us beyond what s possible. Also, God knows everything. He knows what you have done and what you will do.
But there is something not working here. Why does he make us suffer? Why does God doesn't extinguish the pain in the world? The answer to that question is because God gave us the choice to make the good or the evil. God is testing us on Earth to see if we're worthy of paradise. The problem is God ALREADY knows what we are about to do, so why making us suffer on Earth while we could be all together on paradise? Instead, God watches people suffering by all these wars, suicides and genocides.
The only answer to that question is God is NOT infinitly good or just DOESN'T have the ability to extinguish the pain in the world. So I just proved God as we know doesn't exist. But it doesn't prove God doesn't exist. So this leaves us two choice:
1-God is not infinitly love.
2-God cannot do anything in this world since he cannot even save us from pain nor evil.
In any case, I choose to not believe in the God because if he is a liar (1), he would not let live peacefuly those who make evil things against him like satanic people. But God could wait until death arise before giving the punishment so that they have the time to change. But some people give their soul to satan with no possible turning back and yet nothing seems bad to happen to them. So if there is a God, he is truly infinitly love.
So this leads us to the only possible conclusion to our dilemma. God does not have the ability to destroy the pain in the world (2). Then what is the use of such creature? Why should I believe in a creature that can't do anything? Where did that concept comes from? Do we truly have a soul inside of us?
Finaly, there is no exact answer to that question. But the odds are largely against the principle of a supreme entity. But I guess simple words cannot change the beliefs of so many...
