It's logically possible to have Properly basic knowledge (logic, morality, free-will).
If God is logically possible, it's logically possible to have properly basic knowledge of original reality/God.
If we have knowledge of an ultimate great being, it will follow we know God to be unique since we know he is ultimate.
How would we have this knowledge? In the same we can be bestowed knowledge of morality, free-will, logic, all in properly basic manner, God can bestow knowledge of himself in properly basic manner. Even if this knowledge was different, more special, felt different, it can still be properly basic knowledge.
Whether believers know God in a properly basic manner or not, is up to debate.
The proof that he is unique if ultimate, is that it would excel in life, such that there can be no more life then it. If something existed independently of it, it would lack life. But that contradicts knowledge of him being ultimate. Therefore everything exists, exist dependant on him, and he is the source of their life, if such an ultimate being exists.
Does that prove there is no other gods? No, but if there are any, they aren't eternal existence, but created beings whom earn that rank.
Belief in hereafter, we don't know, except that if God is ultimately great, he would not let us just die and disappear. It's also safe to assume he has a plan for us and high purpose in creating us, and that if he is truly ultimate, then he is forgiving, merciful, compassionate, pardoning, and generous and appreciative.
If you are looking for a formal argument, here is one but still relies on the properly basic knowledge of objective greatness or objective morality existing:
1. Greatness to be objective, cannot be arbitrary
2. Objective greatness exists (assumption).
3. If a Creator can decide/create objective greatness, then objective greatness would be arbitrary. (For example, if it can decide rape is great, then it would be arbitrary)
4. Therefore a Creator cannot create objective greatness.
5. If a Creator cannot create objective greatness, then nothing can, including evolution, as a Creator can create evolution, and anything that would be able to create objective greatness.
6. Therefore objective greatness is eternal.
7. Ultimate greatness is included in definition of objective greatness.
8. Therefore Ultimate greatness exists eternally.
9. Ultimate greatness is not separate from consciousness.
10. Therefore consciousness is eternal.
11. Only Ultimate Greatness can fully know Ultimate Greatness (only God can fully know God).
12. Therefore God exists.
1. Morality to be objective, cannot be arbitrary.
2. Objective morality exists (assumption).
3. If a Creator can decide/create what is moral, then morality would be arbitrary. (For example, if it can decide rape is moral, then it would be arbitrary)
4. Therefore a Creator cannot create objective morality.
5. If a Creator cannot create objective morality, then nothing can, including evolution, as a Creator can create evolution, and anything that would be able to create morality.
6. Therefore objective morality is eternal.
7. Morality is not separate from consciousness.
8. Therefore consciousness is eternal.
9. Ultimate morality is included in definition of objective morality.
10. Therefore Ultimate morality exists eternally.
