Wildfire percentages in the United States:
Wildfires can be caused by nature—like lava or lightning—but most are caused by humans. As many as 90 percent of wildland fires in the United States are caused by humans. Some human-caused fires result from campfires left unattended, the burning of debris, negligently discarded cigarettes and intentional acts of arson. The remaining 10 percent are started by lightning or lava

If you're interested, here are some more percentages from my country (Italy). They're from 2001; they're the only ones I could find, so they're a bit outdated, but this year there have been so many fires that the percentage caused by men couldn't have done anything but rise. Anyway:
Like in America, the natural 1,1% is caused mainly by volcanoes and lightning strikes.
When it comes to the hurricane situation and the floods, although it's definitely true that (at least in the US, because if we talk about other areas like where I live it's a different story) hurricanes happen naturally, their intensity is rising because of climate change:
Just about everyone agrees that the amount of rainfall associated with storms and hurricanes is increasing—and the risk of storm surge and coastal flooding is worsening, as well, because of sea-level rise

Honestly, since you clearly can't see the plain obvious, trying to argue with you could very well be a lost cause from the start, so I'll end it here.
