Do you think in a million years when they dig up our remains they’ll see all the skulls with divots from wearing headphones that they will think it was religious or ceremonial thing?

divers? was that supposed to say "divots?" Are there actually documented cases of someones skull deforming from wearing headphones enough? I have never heard of such a thing.

Headphones are not leaving divots in anyone’s skulls

Divers wearing headphones? Regardless, I suspect that after a million years there won't be much left of the headphones.

I think headphones aren't tight enough to leave divots, but cochlear implants might make them wonder.

Of archeologists don't know it: "for religious reasons".

No, I don't think headphones will changes the skull, unless you put them on a newborn. But I do wonder how much information could be lost, given how much of it is digitalized nowadays.

I expect them to dig up people with curved pinkies due to holding phones all day

yes
