All opinions are not equal. Some are a very great deal more robust, sophisticated and well supported in logic and argument than others.
-Douglas Adams, The Salmon of Doubt

I can be proven wrong. And this makes me more likely to be right than one who cannot be proven wrong. I want to be clear about this. So let's restate that assertion. A statement that can be subjected to tests that could disprove said statement is more likely to be true than a statement that cannot.

Why?

Because every time the first statement  is subjected to one of these tests, it becomes more accurate. If the test fails to disprove it, then we know that the statement is accurate in the way that the was tested- and new tests looking at the statement from alternate angles can be devised. These new tests can even test the same element of the statement but in a different way or from a different angle, to test the assumptions of the first test.

If the test disproves the statement, the statement can then be revised based upon the information gained from the test regarding HOW the statement was incorrect. The statement can then be examined, rebuild and tested again.

A statement that cannot be tested, cannot therefore become more accurate. Such a statement can only defend itself by pretending that not changing is a virtue- but only the abstract can remain unchanging. Life changes in order to remain alive. A frog in your pond is not the same frog you saw yesterday-even if it is- because the frog is now built from new flies and insects, composed of new atoms, deteriorated further by the entropic breakdown we call aging. Every time you remember an event from your past, the memory itself changes by the act of you remembering it- but the memory disappears entirely if it is not accessed.

We should distrust any idea that seeks to protect itself from inquiry, and act as a dam against the flood waters of change.

I am fascinated by religion. (That's a completely different thing from believing in it!) It has had such an incalculably huge effect on human affairs. What is it? What does it represent? Why have we invented it? How does it keep going? What will become of it? I love to keep poking and prodding at it. I've thought about it so much over the years that that fascination is bound to spill over into my writing.
