Link to pdf research publication regarding tattoo markings on preserved body from 3,300 BCE which concludes:

“A treatment modality similar to acupuncture thus
appears to have been in use long before its previously
known period of use in the medical tradition of ancient
China (c 1000 BC, see refs 11, 23). This raises the
possibility of acupuncture having originated in the
Eurasian continent at least 2000 years earlier than
previously recognised.”
