Have you been outside before? I mean like walked around in nature and stuff. Nature is pretty good at catching fire from my experience.
I was in Yellowstone during some of the more recent widespread fires (not nearly as badly as the 1988 ones though.) I lived in the Midwest for most of my life, where there were controlled burns of prairies that became not-so-controlled. Some forests went up like they were made of matches. Unattended campfires, careless smokers, sparks from train brakes, power lines, criminal intent, fireworks, signal flares... There are all kinds of human-started ways for fires to consume a forest. One thing about human-started fires, however, is that usually someone isn't far away from it when it starts so the response time is better (a lightning-strike fire can go unnoticed for a while depending on the size of the forest.)
I mean think about this: if you go camping (I'm assuming you haven't) what do you do to start a campfire? Start with small things to burn, like pine needles and small sticks and smaller flammables. The things that make up the forest floor, which are the things most likely to come in contact with people normally. Then you move up to logs, which, last I checked, came from trees. The forest is generally made of those. So yes, water content may be different (dried wood burns better) but once kindling gets going and there's a significant source, pretty much anything will burn.
Oh and don't cite Rush for anything meaningful, except maybe draft-dodging. That guy suffers from a debilitating case of rectal-cranial inversion.
(I'm hoping you're a troll and you used Rush's name to get a rise out of people. But sadly there are a lot of people who think like this... Ho hum. Poe's Law.)
Also, urnil fnepnfz? Huh?
