ELI5: What is Natural Gas?

When one refers to the fossil fuel "Natural Gas" is that substance in a liquid or gas state? I honestly don't know if the gas that comes out of the stove is harvested from the ground in in a gaseous state. (Or if it is even harvested from the ground at all)

Usually it's pockets of gas trapped underground.

when petroleum oil is formed, a by-product of the oil is the gas.

When we drill for oil, sometimes a huge high pressure pocket is found, and if it's pressure is high enough and sustainable for a long time, we will just tap it off and use it. (There is some processing done to it before we use it) but in a nutshell that's basically it.
