How do you research?

Sorry if I'm using the wrong flair for this.

How do you research? Or do you even research? Do you read books by modern witches/neopagans or do you work more with your own ideas?

I mostly work with nature as I have a hard time making any connection to pagan deities. Usually for me, I need proper sources to "know" if I'm practising witchcraft with misinformation or not, which can be really hard, because the archaeological and historical record is often inaccurate, like in the Interpretatio Romano, or modern creators putting their own opinions in their info posts. I often find myself falling into rabbitholes of papers, articles and creators saying something different all the time.

I have tried working with Gaulish deities, but it is difficult to believe in them if I am unsure of the ancient traditions...

Anyway Im hoping to read about yalls approaches to deity work and how or if you research!
