Pilot gas is the very small flow/burner used to maintain an ignition flame in a gas appliance. Sometimes called a pilot light, or pilot flame, it's used to ignite the main burner.
so when the pilot goes out the gas valve is shut off
The gas furnace pilot (flame is lit all the time) is sometimes referred to as a pilot light, but no matter what you call it, its purpose is to serve as a small ignition flame for the gas burner. And when this little flame fails to operate properly or go out, it's one of the most common reasons a gas furnace will fail to operate.
modern heaters have a thermocouple that would shut off gas supply if the pilot goes out.
When pilot light goes out, gas flows out of the pilot light nozzle. If out has continued for a long time, a gas cloud can develop around the furnace. When you go to light the pilot light, you'll ignite this gas cloud and make a big fire ball. If your basement is drafty, you might never get a huge cloud of gas hovering around your furnace. When you notice that your pilot light is out, you should shut off the gas to the furnace and allow any stray gas to dissipate before you turn the gas back on and light the pilot light. alliedallcityinc.com

How do I light pilot light on furnace
Perhaps the pilot light is out and the gas has been turned off at the valve.
There are always very detailed instructions on the regulator. Read and follow them.
Remove the pilot assembly from the furnace and clean it up. You need to be careful when putting it back on at the gas valve so as not to crossthread the screw. Take a thin wire and clean the pilot orifice, then use a brush or sandpaper on the thermocouple.
