Now, this is a very fun one.
Imagine that you have a box.
In that box, there is 50% chance that there is undetectable God in there.
I say 50%, because God either is in that box or isnt. With both options being equally not proved, their probability must be equal.
So 50% chance that God is in the box.
Now imagine another box which has 50% chance of containing a different undetectable God, following same principle.
So now we have two boxes, each having 50% chance of containing some undetectable God.
By probability, there is 75% chance that at least one box contains God, because there are only 4 options:
1. Both boxes contain God
2. No box contains God
3. First box contains God, while second doesnt
4. Second box contains God, while first one doesnt.
So there is only 25% chance that no box contains God.
Same argument also works with any place and also with any time. Whats interesting is that the more boxes you add, the probability increases due to this simple law:
In order for no God to exist, each box must contain no God, while in order for God to exist, only one box needs to contain God. So basically, "no God" must be true every time in order to be true, while "God" must be true only once in order to be true.
This statistical advantage always favors God.
For example, in case of many Gods:
1. God one exists and God two exists
2. God two exists, while God one doesnt
3. God one exists while God two doesnt
4. God one and God two dont exist.
So statistically, the moment you add multiple places, or multiple Gods, or multiple time periods, the statistical probability of God existing greatly increases.
This is also problem for atheists in other areas. For example, atheist must be right every time to defend own position, while believers need to be right only once to prove their case.
It is not possible to prove that God doesnt exist, thus chance is by default stuck at 50%. Atheists must disprove every single evidence which all theists bring up just to keep chance at 50%, which is why atheism is at a statistical disadvantage in terms of evidence. Also, due to limited knowledge, what cannot be explained by science or knowledge can only be explained by supernatural, and this is another problem because theism gives more answers than atheism.
Even if atheists claim that everything can be explained by natural causes, the problem is that probability argument works against atheism here, because if there are 10 cases which can only be explained by supernatural, even if we assume equal probability of natural explanation existing in each individual case, the chance of supernatural explanation being correct in at least one case out of 10 cases is over 90%.
This is simply because mathematically, if we apply equal probability to each individual case, which we must, we end up with probability increasing as number of cases increase.
Its like saying "if you flip a coin, thers is 50% chance you will get heads." But if you flip it more than once, probability of getting at least one heads increases.
