ELI5: Why is light considered analogous to time?

In every video I see about time relativity, they explain it by showing that light bends due to gravity. But why does that imply that time bends as well? Isn't light just a collection of photons?

The light is just there as an example. If the light were not there, space itself would be bending. Space and time are part of the same thing:spacetime. 

By having the light be present, you can see the path and curvature of spacetime. The speed of light is the speed of all causality (it’s just that light is the most obvious thing that always goes at the faster possible speed). If the path of light is disturbed due to the warping of space, then time in inherently changed.
