Just as an imaginary language Proto Indo-European was created by Western Padre Linguists to explain the presence of Sanskrit words in European languages, the same way this "GapodBazi" of Indians borrowing astronomy knowledge from Greeks and Babylonians has been perpetuated.

For details see Kalakriya-pada, vss, 17-21. |
The eccentric and the epicyclic theories of Aryabhata I have been explained in greater detail by Bhaskara I in his Maha-Bhaskariya (ch. iv)........

The Greek astronomer Ptolemy, too, explained the motion of the planets with the help of epicycles and eccentric circles, but the method used by Aryabhata I for explaining the planetary motion is quite different and much simpler than that used by Ptolemy.

Bina Chatterji who has made a comparative study of the Greek and the Hindu epicycles and eccentric theories, concludes that ‘“Aryabhata’s epicyclic and eccentric methods are unaffected by Ptolemaic ideas".

It may be pointed out that whereas the epicycles of Ptolemy are of fixed dimensions, those of Aryabhata I vary in size from place to place.

The variable (or pulsating) epicycles probably yielded better results, The later Hindu astronomers have followed Aryabhata-I in taking variable epicycies.

Aryabhata-I states that
Circumference : diameter =62832 : 20000,
which is equivalent to saying that π=3.1416.
This value of π is correct to four decimal places and is better than the value 3.141666 given by the Greek astronomer Ptolemy.

It does not occur in any earlier work on mathematics and constitutes a marvelous achievement of Aryabhata-I.
It is noteworthy that Aryabhata I has called this value only ‘approximate’."

I guess 3000 years from now Indians would have borrowed and learned Yoga from Westerners. ☺️☺️
