Where did all the carbon come from, before it was trapped as fossil fuel ?
Not from the plants and the animals that make up the fossil fuels, but what provided the carbon to make all those animals and plants in the first place ?
It's all just a matter of your timeframe.
500.000 years sounds like a long time to us.
It's nothing in the geological sense.
What is normal on Earth ?
Many tend to see it as the Earth they see NOW, but is that the case ?
This shortsightedness goes as far as people building on vanishing cliffs - cliffs that have eroded for ages, but may look sturdy when seen in a very restricted timeframe.
One thing is constant, and it is change itself.
Mankind tends to opposes change - any change - and sees it as a problem.
We attribute far too much importance to ourselves.
Earth doesn't need us.
Like it didn't need the other 99,9% of extinct species that went before us.
