Yes. Ignorance is the problem. For most people. A few people are simply insane. No amount of knowledge will convince them to believe anything other than what they have deluded themselves into believing. They need psychological treatment before they can escape their delusion. But most people will believe what's true if they have enough information.
The required information comes in two respects: people must not only have more information, they must know how to reason from that information coherently (without fallacies or errors of thought). The latter is itself a body of information, namely information on how to reason coherently, how to prevent or detect and correct errors of thought, and why. It comes in the form of studying logic, psychology, and empirical method.
The human mind is actually built erroneously, it errs in a number of well-documented ways, which we can explain as byproducts of a blind process of evolution, but which we still must overcome by learning and developing the skills necessary to catch those errors and avoid or overcome them. Once we've done that, then we can start gathering more and more information (from science, history, and personal experience) to test the claims of different worldviews, and then, armed with those skills for avoiding error, we will be able to discern which worldview is most probably true.
The end result of this process will be the discovery that only atheistic naturalism has any credible probability of being true.
