There is a YouTube and website called Alien Carvings, a researcher looking at a lot of unearthed artefacts, alien looking artefacts. Vases, art and all sorts of pieces.
In this video it shows a bunch of artefacts with the buga sphere chip which is super interesting.
Not saying they are legit (I want them to be) not saying they are fake just pointing out how interesting it is and everyone should have a look see.
