3. They have no purpose
Start:
1. Good God created horrible world
A very simple one. I dont mean to insult anyone, but anyone who thinks that good God can create horrible world lacks a working brain. Anyone who thinks that the world is good also lacks a working brain.
2. We are not all same
This is probably the most obvious proof against God. A good God would create all people same so that they can show that they are good or bad under same circumstances.
But no.
Some people live a horrible life, while some live an easy life.
So if God is giving people a chance to prove how good they are, he is not giving everyone the same chance, so we can simply deduct that there is no God stupid enough not to know how testing works.
Making some people be born blind, deaf, mute, disabled, die early...ect., God shows no consistency in his testing, thus his tests cant even yield results because a person blind for whole life is prevented from looking at a woman and doing a sin of looking at a woman with lust.
A person who dies early, for example, as a baby, you can never know if he would actually be good or bad later in life.
If you do know, then there is no point of testing to begin with.
3. They have no purpose
A bunch of people in this world have no actual divine purpose. They are neither smart, neither good, neither humble...ect.
Basically, under common understanding of religion, God created these purpose-less people, they do evil and then get thrown in hell.
Since God had no logical reason to even create them, their mere existence negates the God creator.
