Why is that amount “infinitely small” and not 0 since photons travel exactly at the speed of light?

Existing for zero time would imply it never existed.

In the mathematics of infinity, something can have exactly zero probability yet still happen, and exactly one probability yet nonetheless fail to happen (hence the standard term “almost surely”).

If something can have literally zero probability of existing yet still exist, why can’t it exist for literally zero time yet still exist?
