Might there be “undiscovered” explanations which are even more reasonable than God?
that might be. In this case, we will be condemned to eternal ignorance of the most fundamental questions of our existence. But the bible says, who searches God with a open heart, he will reveal himself to that person. I experience that, but it is a personal experience, therefore i cannot use it as evidence . I can just testify that God revealed himself to me in many ways. And that is one of the reasons, i believe that the God of the bible is the true , living God, creater of the heavens, and the earth. But there is not only my personal experience, but there are many other reasons, that have made my faith in this God to be as strength as it is.
