The IVC civilization collapsed and its cities disappeared, and is a matter of debate how much contribution the IVC contributed to later Indian civilizations. The names of IVC vanished from memory, their advanced sewer and drainage system vanished with them too. When cities re-emerge in India, it was after China and Greece.
So if you include the Indus Valley Civilization, yes, it is older than China, but it you don't, then India should be placed after the Greeks.
The Greeks should be on that list, ahead of the Chinese I think or tne same. The Minoian and Mycenaean civilization was contemporary with IVC, and about the same age or slightly older. The cities and architectural elements of the Mycenaean and Minoan civilizationa were more advanced, the writing more extensive than found for contemporary China, and tne bronze and metal work as good. True, the Mycenaean civilization collapsed, but unlike the IVC, they did not vanish without a trace, but left a legacy that tne Greeks rememberd. Also, unlike the IVC, some of the Mycenaean cities still remain inhabited.
