How many years of natural gas is left in the world?

I'm curious to know, given the current rate of consumption and available reserves, just how many years of natural gas are we looking at left in the world? Is it a matter of decades, or could it potentially stretch into centuries? And what factors, if any, could impact this timeline, such as advancements in technology or changes in global demand? It's a pressing question, given the critical role natural gas plays in our energy mix and the need to plan for a sustainable future.
