Religion is another way of knowing
Stating "religion is another way of knowing" is an appeal to an egalitarian impulse for equity. It constitutes an argument by pathos. It also constitutes a support of relativism.
This argument claims the God of the gaps argument is true, and that they know that it is true. The argument is a God of the gaps argument because they say that god did everything, and they know it. This is odd as it is commonly raised that you can't know everything by both sides.
Consulting a Magic 8-Ball is also another way of knowing. Or, to make it more general, guessing is another way of knowing.
The question then turns into "How do you know that this knowledge is true?". Using the word "knowledge" might look like it implies that the data is true by definition, but this is not the case. We can read the Harry Potter books and gain knowledge about Harry Potter and the world in which the story is set. It is knowledge, and it's true in a sense that it is true to the description given in the book, but it is not a description of a real, existing world; it's not really true.
Science purposely has mechanisms and procedures to verify and confirm collected knowledge, whereas religion does not. Religion makes claims to knowledge, and sticks to those claims no matter what.
