I would like to know the percent of fires “set” as opposed to caused by nature. Bet it’s 50/50 or higher.

I don't know the number, but have seen some interesting figures on the number of wildfires set by firefighters - it's pretty embarassing so publicity is limited, but it's pretty shockingly high.

Same with house fires. This is especially true of volunteer firefighters.
