Ancient calendars?

Is there more than just a chance resemblance shared by Göbekli Tepe, the Anykthera mechanism, and stonehenge, regarding earth solunar cycles? Check it out for yourself:

Stonehenge (rotated) overlapped on the Antikthera mechanism:

Aside from some similar angles I don't see too much overlap, but interesting to compare 10,000 & 5,000 year old large earthworks to a small astronomic 'computer' from the Archimedes Greek period of 2,100 years ago.

BTW, words from very different languages overlap via common descent:
top/tip/up/alp - above
tipi/teepee - Dakota cone tent
topi - Malay, Hindu - dome skullcap
tepe - Turkish (hill)
tepec - Aztec (hill)
tila - Assamese (hillock)
o'por - Assamese (upper/over/above/upon)

tip top vs pit pot (sound & position inversion) bottom, boat, bottle, butt, tub
tip chip vs top chop (small vs large)
