Q: In Admin → Events, when do I use 'Create event' vs 'Modify event'?

A: One spawns a new event, the other rewrites an existing one.

— Use Create event to generate a brand-new event from an existing one — e.g. fire 'generate_lead' whenever page_view has page_location containing '/thank-you'.
— Use Modify event to change parameters on events already coming in — e.g. fix a typo in a value, or overwrite a parameter, without touching new event names.
— Order matters: modifications run before creations, so a Create rule can read a value a Modify rule already fixed.

TL;DR: Create = make a new event from a condition. Modify = edit parameters on existing events. Use them together for clean naming without code changes.
