Content created - original date metadata carried when exporting in PNG

Hello,

I've looked everywhere and can't find any answer about how can I keep the original date when exporting an image as PNG. so that when I open the folder of edits in Finder, for instance, I can easily see as 'Created' the original date and 'Modified' the date it was edited.

I hope you already have a tool or a way to include this in the metadata and I appreciate your guidance to find/learn it.
