What do you mean by layers ?
….
Layers meaning there was an original document used as a template, and it was photoshopped with other fake information on it. Maybe someone else can explain better.
In graphic design you create separate layers for text, images, etc. Like putting a logo for a real estate company over a photo of a house, the logo and the house are basically stacked on top of each other. In the “birth certificate,” there were separate layers of text in various areas. Whoever put it together forgot to flatten the image, so the layering wouldn’t show.
I hope all that is understandable. It’s past my bedtime! :)
