writing can capture different information, and the fact that much of what we do have is religious is tied to the fact that writing was so rare!
If you personally dont find the history of human belief interesting, think of something you might. What if you could read journals from explorers settling the pacific islands. What would a daily journal from a 20k BC Mesoamerican include? What did people think about sabertooth tigers,
Without translations it's not useful either. I'm not against writings but we can glean way more info from DNA and archeology than glyphs. Pictographs are useful but long dead writing methods aren't interesting unless we can understand them.
Obviously that depends on what you want to learn. DNA is not going to tell you the hopes, dreams, or thoughts of early peoples. I have zero care for information as a general concept. I care about specific types of information.
The funny thing about translations are that if you have lots of texts, it makes them easier to translate
