It can be a lot to think about but suppose...
At some point we are somehow informed, we have a simultaneous revelation or epiphany that we are right. All forms of belief are correct. I think it is possible.
That we could find out that yes, the universe is full of love and hate, good and bad. The choices available can be both right and wrong.
That the different manifestations thought to be God, all are. All scripture is also true and the only thing that changes is perspective. And even atheism is correct in that everything is everything and always has been and it is OK to call God or not.
It's hard to get this out in any sensible manner, but I swear it looks right swirling around in my head.
This is known as subjective or relative reality, and it is self-refuting (but makes for a worthwhile discussion, usually).
The reason this proposition is self-refuting is that if the truth is that all reality is subjective, then the objective fact regarding the universe is that everything else is subjective. So, it still is ultimately objective. Someone who correctly identifies this fact (assuming it was true) would be more accurate than someone who did not.
In other words, say both Allah and Krishna exist. Would both Muslims and Hindus be right? Well, not really. Many Muslims claim that Allah is the only god, so they would be partially wrong. Hindus may acknowledge the existence of various gods, but would reject the notion that the Qur'an is the ultimate and complete word from god. And if either of these gods exist, then atheists did not have a correct view of the world either, because they didn't believe in any gods yet all gods do exist.
And if a subset of Christians claims that
only Jesus can lead to salvation, but it turns out that the Noble Eightfold Path of Buddhism can lead to salvation too, then this subset was partially incorrect.
Basically, because many religions (and non-religious philosophies) make objective claims regarding the universe, and a lot of them logically contradict, they inevitably cannot all be correct. Some will inevitably be more or less accurate than others.
It's worthwhile to note, though, that people of different perspectives could have equally correct ways of analyzing information, even though they differ. If two people have different beliefs, but both came to their beliefs due to rational reasons based on the information that was available to them (each person would have a different subset of the total available information), then each person may have been "right" for believing what they did even though they were wrong about the universe. Their methodology may have been appropriate and reasonable, yet ultimately lead to the wrong conclusion. Different people have different levels of understanding and appropriate methodology, and have different degrees of worldviews and are more skilled when it comes to acknowledging their level of certainty regarding a thing. Some have small worldviews while others are aware of and knowledgeable regarding several worldviews.
