The Pali version isn't quite as strong. According to Malalasekera:
Immediately after birth the Bodhisatta stands firmly on his feet, and having taken seven strides to the north, while a white canopy, is held over his head, looks round and utters in fearless voice the lion's roar: "Aggo 'ham asmi lokassa, jettho 'ham asmi lokassa, settho 'ham asmi lokassa, ayam antimā jāti, natthi dāni punabbhavo” (D.ii.15).
The meaning of the phrase is "I am the highest in this world; I am foremost in this world; I am the best in this world; this is the last birth; there is no further becoming here."
Nothing I've found specifying heaven and earth; it also doesn't seem proper for the Bodhisatta to have said "I alone am honoured", since it is patently untrue.
