Why did god krishna born in north india ?

The story of Ram Chandar Maharaj is traced entirely in the areas now called Pakistan. Sits Kund, Ram Kund, Lachman Kund; The cities of Lahore and Qasur (founded by sons of Ram Chandar Ji) the temple of Mata Hanglaj and the taapu that is an island within Rann of Kutch which was then as wide as the Persian Gulf. Sri Ram Chandar ji belongs to Pakistan. I am not sure of Krishan Maharaj. Not aware of his traces in the North of India (Pakistan). Rig Veda was written at the bank of River Ravi near Lahore. Katas Raj temples in Pakistan are said to be the oldest existing Hindu temple in the world. L K Advani had visited the temple to thank Govt. of Pakistan for earmarking large Funds for the restoration and upkeep of the Temple. South Indians claim that Hindu religion is basically Dravidian with Tamil origins. May be there were two religions merged into one!
