There are many disproofs of Christianity. I will use just one here. This disproof of (Protestant evangelical) Christianity is based on a question I asked when I was about 9 years old.
Rather than argue about Biblical errancy or finer points of doctrine, I will go right to the heart of Christianity. Christianity could be summed up as "Believe that Jesus existed and is the son of God (the old testament God) and you will go to heaven otherwise you will suffer eternally in hell". Now as part of my disproof we also need to include the Biblical claim that "God/Jesus is just and good".
Doctrine 1 "Believe that Jesus is the son of God (the old testament God) and you will go to heaven otherwise you will suffer eternally in hell".
Doctrine 2 "Jesus-God is just and good".
The disproof of Christianity is that both these doctrines cannot simultaneously be true:
Think about a child growing up in Africa who has been indoctrinated with local tribal beliefs from a young age. He never hears about Jesus. If doctrine 1 is true then he will suffer eternally for what is essentially an accident of birth. That is the opposite of justice, so Doctrine 2 is false. Therefore Christianity is false.
Now for my reply to a common response to this argument:
It has been said God will make special allowance for those ignorant of Jesus. Well if that is the case it is far better to never hear about Jesus. If you never hear about Jesus you are guaranteed heaven. Telling someone about Jesus means there is now a risk of hell for them if they do not accept it. Jesus encouraged the spreading of the gospel so he was increasing the numbers of those hell bound, therefore Doctrine 2 is still false. Therefore the argument still holds that Christianity is false. (Note: the doctrine that God will make special allowance for those ignorant of Jesus, is not based on scripture - it was just made up because of this disproof which I'm sure has arisen many times independently.)
To conclude, if the rule is that someone who has never heard of Jesus goes to hell, Christianity is false. If the rule is that someone who has never heard of Jesus goes to heaven, Christianity is false. Whichever way it is, Christianity is false.
In addition, the lack of clarity about the contents of any such rule (there is no consensus between denominations and even between individual believers) means Doctrine 2 is false. A loving and fair deity would need to make it absolutely clear what the requirements are for something as important as eternal fate.
If, like many liberal Christians, you recognise the implications of this argument, you may state that hell does not exist. That means that when Jesus referred to it in the gospels he was mistaken or lying or the story of a Jesus saying it is wrong. That route leads to a whole new debate as to what criteria should be used to pick and choose which parts of Christianity are true and which should be discarded. The logical conclusion of such debates/thinking is that none of it is true. That is the journey I took when I was quite young. I saw that it cannot all be true so I started to ask which bits are true and how can we tell. What criteria do we use and why should any of it be true?
* This disproof can be applied to any other religions that preach punishment by a just and loving deity for disbelief in the just and loving deity.
