You see, yes, petroleum is remade at extremely slow rates, oil starting to be made millions of years ago, so the relative amount developed compared to the amount used is not sustainable.
Better to know what you're talking about than making broad, sweeping statements that don't hold water, let alone oil.
https://money.cnn.com/2016/07/05/investing/us-untapped-oil/index.html : "All told, the world has 2.1 trillion barrels of
untapped oil, or 70 times the current global annual
production rate, Rystad estimates. ... That's a big deal given the fact global
oil demand continues to grow, even in today's sluggish economy."
That quoted 2.1T barrels is just what we know about. As Mark Twain once said, "It ain't what you don't know that gets you into trouble; it's what you know for sure that just ain't so."
M. King Hubbert, a Shell Oil geologist who likely never read Twain, predicted in the 50s that we would exhaust our oil reserve by the 70s. He was dead wrong, and he is also dead, period. Yes, oil/nat gas/coal take millions of years to produce, but that does not mean the process has been going on merely millions of years. The Earth is over 4 billion years old. That's 4,000 million years. And, once begun, the process of making continues, unabated for as long as there are living organisms on earth to make the stuff.
Your 8th grade experience notwithstanding, you were duped by an agenda that continues to this day. Teachers are not gods, and most of academia is led by the nose without applying much critical thinking to what they are taught and vomit to you.
The same problem occurred with teaching you about over-population. We do not have an over-population problem, we have a resource [including food and water] distribution problem that is fed mostly by greed. Why aren't we using more agricultural land to actually grow crops [we use about 14% of available land, worldwide, for that purpose]? Why aren't we desalinating ocean water? It's a grammar school tech level. Why haven't we built aqueducts from the confluence of the Mississippi and Missouri Rivers toward the southwest of the U.S. to provide water there, and to lessen the flooding further south? Why am I limited, by law, in my state, to having a fresh water cistern of underground storage of only 2,500 gallons [which I have], when I could triple and quadruple that storage amount, and more? Greed, my friend, is your problem, not over-population. There are resources in abundance available to us, even in a greater population, but politics trumps science.
