Try lighting a campfire at night when all the wood is completely soaked.

Which is why you look for old growth stumps and pieces left behind as well as fire/lightening struck ones one the ground, for pitch seams and the thick bark both of which will light after rain. Pitch burns hot enough to get dry evergreen branches to burn - those are easily cut off standing dead wood. More, if you know what you are doing and the resources available in the woods.
Fatwood is what you need to find, if you know where to look. At the base of dead trees or where the branches meet the trunk. It has an amber color and smells like turpentine, is hard to chop but lights even when wet. But I’m not an outdoor survivalist, any more than these guys apparently.
Find your fire starter along the river where the wind always blows. As boy scouts we could start a fire in a swimming pool.
