(unindent) As Steve points out, the notion that Greek astronomy influenced Indian astronomy is well-established.  This is moreover backed by a plethora of sources . Only Hindu-nationalist chauvinists contest this.  That the idea of a spherical source arrived to India from Greece is not ridiculous, it is well-sourced to the most reliable of sources (Pingree, David "Astronomy and Astrology in India and Iran" Isis, Vol. 54, No. 2 (Jun., 1963), pp. 229-246).  What's ridiculous are your empty, original-research denials.  As for the fact that Yavanajataka specifically means "Sayings of the Greeks", again that is reliably sourced (David Pingree, "Jyotiḥśāstra", Jan Gonda (ed) A History of Indian Literature, Vol, VI Fasc. 4, Otto Harrassowitz - Wiesbaden, 1981) and .  As for the Yavanesvera, that too is a Alexandrian Greek text that was introduced into India, and that too, is sourced .  And please don't use crap like this [ , it only serves to undermine your credibility further.  Now, I am going to reintroduce into the lead that Indian astronomy was influenced by Greek astronomy, and I expect you to abide by that.
