Lacking any cncrete evidence.sme even claim it was supernatural pwers!
Scientists, hwever, dispute these theries. It’s mre likely, they argue, that civilisatins arse n the 30th parallel nrth because the climate there is generally warm and wet. Majr tectnic plates meet at this latitude, causing earthquakes, which helped frm the Himalayas. The rest, they say, is eithercincidence r fantasy.
