The world’s oil supply. Finite. ~ 1.73 trillion barrels
The world’s oxygen supply. Infinite. It’s endless.
The universe is not a static measurement of space/time,it's expanding faster than the speed of light which means there's no way to make a snapshot (measure) .
We can't observe the expansion itself,we can measure it's effects on the relative distance between objects within space/time.
Infinity is our inability to measurably create snapshots of anything beyond three dimensional space.
