Imagine I had a length of string that was infinitely long. What evidence or argument could I present that would convince you that it was infinitely long? Of course, I could show you vast warehouses in which some of it was stored, but we cannot inspect an infinite length in a finite time. On the other hand, if it were of finite length, it is usually easy to demonstrate that.

An easier demonstration of infinite properties might be an object traveling at infinite speed. However we might only interpret this as something being in two spatially separated locations at the same time. We still have the difficulty, given the imprecision of measurements, to be able to distinguish between a very fast particle and an infinitely fast object. If the object has finite speed, it is certainly feasible to determine its speed as finite.

Properties that may be infinite cannot be practically distinguished from similar, very large but finite possibilities. I came to this conclusion when I was asked what evidence it would take for me personally to believe in God. The traditional conception of God includes various infinite qualities. I think it is conceivable that I could be persuaded that were was a powerful, creating entity. But can we distinguish between a powerful finite God and an infinitely powerful God? By analogy, we can argue that God is not infinitely powerful, since in our experience of reality there are only finite things (finite size, finite knowledge, finite precision, finite mass, finite duration). The only other defensible position seems to be a skeptical one, in which we claim God may be finite or infinite but we could not come to a determination either way.
