No it is not.
We experience a subjective reality. Objective reality probably exists, but we can't confirm it. What we can do is share our different subjective experiences, and the more that they line up, the more we define them as "true" and reliable. But everything is always up for revision. That's the scientific method, basically.
Religion is holding to an "understanding" even when others' experience goes mostly against it.
