I am very interested: What would be the reason?
Christians might say it does, or that you are with god before being born, but you don't remember it.
Or, that you are created in the womb, on Earth, and you are endowed with original sin from the seed of Adam, and that god can not show himself to you until you are baptized and freed from original sin (because God is perfect, and the perfect can not exist where there is sin).
Or a thousand other ad-hoc justifications. It's all completely fabricated, but it's largely internally consistent.
The reasons we know gods do not exist are more fundamental logical, internal, and empirical contradictions in their prescribed natures.
Omniscience vs. Physics (Relativity and causality- no time travel)
Omniscience vs. Logic (information/incompleteness)
Prescience vs. God's Will/Free Will
Free Will vs. Logic (it's complicated, depends on the definition)
Omnipotence vs. Logic
Omnibenevolence vs. God's Will
Validity of Moral dictate vs. Logic (Euthyphro)
Omnipresense vs. Physics (Relativity and causality again)
Creation vs. Logic (Acting without time)
Those, among a few others I may have missed, are why 'god' doesn't exist.
...Not because there are lingering questions regarding the nuances of soteriological rules and divine motivation, which are easily resolved by any number of possible answers (ass pull or not), and basically useless because it just lets the theist know that the critic did not RTFM (all of this stuff is basically answered in standard apologetics fare with borderline plausible made up stuff).
They're called Theodicies, and the're a fundamental of apologetics.

Why is that the center of apologetics?
Because those are the only questions most people get up to asking.
Possibly the only questions most people really understand well enough to ask- although that might be an overly pessimistic view of humanity.
People don't naturally deal well with logic or science. They personify, and they deal intuitively in emotions- so the emotional questions, the ones of motivation, are the ones they ask most readily and with the least difficulty.
And thus, theodicy.
But that's not something an atheist can bring to bear against any serious apologist- apologists who do have far higher IQs than some might give them credit for.
