Depends on how you define great. If conquering and cnquests are termed great , then yes . If the self advancement is termed great then a big NO. The Rig Veda was way more enlightening than the Ancient Greek scriptures. Indian epics are far longer than Greek epics. History records show that Indian literature evolved before Greek Literature. India had scholars like Kautilya, Buddha, Mahavira before the Greeks had plato,archimedes or socrates in recorded history . Now I am going to give an evidence that will support my claim further. The oldest universities of the world were in Ancient India at a time when even the persians were busy fighting the greeks. Current dating suggest Taxilla and Nalanda to be atleast 200 years older. That would make these Iron Age universities during 800 to 900 BC and it existed till 7th century AD. By the time plato had formed his philosphies , Arthshastras ,upanishads were already written in India . It is much more possible that much of this spiritual knowledge travelled to Greece.
Take a real life example. If you know the world’s best university is Oxford , would you go to Oxford or would Oxford come to you ? Do you realise why India never really went outside the subcontinent . Because they had everything here. This coincides with the Indain philosophy of know yourself first. The Greeks had a similar philosophy but they went outside . This shows that the philosophy formed much later.
The Greeks are popular because the romans spread them forward and the greek revival scence. India got suppressed because of foreign muslim and christian invasions. Modern day Cognitive science implements Indian Yogasutras and the concept of Lucid dreaming also came from Indians and Chinese.
Whether the Greeks are more advanced than Chinese , I do not know as the Chinese can only say that
