The problem is when you focus on a narrow time aspect.
And then couple that with "we live on a ball of earth hurtling around"
So, we assume that there is only x amount of any material.
And, this is more or less true
But, as technology progresses we use different materials.
How much whale oil did you buy this week for your lamps? Kerosene put a stop to that industry...
Further, we seem to be living on an expanding earth. The earth is making more material.
