Who could start and build a a fire with a fire starter only?

I can tell time by the sun a few different ways. One way is holding your hand sideways level horizon then keep adding fingers till you reach the sun. That will tell you how much daylight you have left

Look at shadows and their placement tells what hour it is

Where the sun is sitting in sky

At night, look at the moon, where is at in the sky

Speaking of the moon. The shape of moon will tell what week of the month it is. If you know that. Then aline with with the north star and figure out what day it is.

What about cloudy days listen to the frogs, bugs and other animals. Watch and study them. Become one with nature

Can I start a fire? I can a fire with nothing in pockets and searching for what I need.

I took survivalist wildness training in my late teens though my early 20s for like 6 years. I still practice the skills today and teach them to my grandkids. Never know when they might need them skills.
