Have you ever started a fire without using fire making gadgets?

So the OG way to make fire is using things you can find in the wilderness, have you ever tried to make a fire without using lighters, or any form of incendiary tools?

Years ago my friends and i after eating a pizza we made a fire in the pizza box, we used the pizza box to hide it from everyone cause it was in the middle of a complex infront of many balconies but we used two rocks and dead grass and dry bark and we hit the two rocks together til a spark fell on the kindling, we fed the fire til it got too big so we ran with the flaming pizza box to the closest body of water that's the day we realized we would not die in the wilderness. πŸ™‚
