You know the game. The last liar has to tell the bigger fish tale. This is especially true when it comes to religion, gods, and spiritual matters. Who walks on water and who feeds more people with little or no resources? Let me answer that question with a couple of historical facts. Facts!
In the Jataka Tales, a voluminous body of folklore and mythic literature, concerned with previous births (jāti) of the Buddha, there are some 547 poems. Taking into account archaeological and literary evidence it seems likely that they were compiled in the period, third century BCE to fifth century CE.
Most probably well before Jesus came to this earth.
Amongst these writings you find the story of how the Buddha fed 500 people with just a bowl full of bread and yet he had (you guessed it) twelve baskets left over.
The Gospels Mark (Chapter 6), Luke (Chapter 9) and Matthew (Chapter 14) have a very similar story about Jesus feeding, not 500 but 5,000. My dad can beat your dad, you know. 
Jesus walks on water!
In the Mahavagga, we find the story of Buddha walking on water several hundred years before Jesus. In the Apocryphal Acts Of John (93:9) John senses that Jesus sort of skims across land and water without leaving a footprint. Now that’s new!
What’s not new is every religions God out doing the others.
So, they were telling the traditional stories that were used to establish divinity?
If so, is there still anything we can glean from them, since we don’t need them for that purpose?
Absolutely. Metaphors are truthful and even more helpful than TRUTH- though they are not FACTUAL! In this case, YOU CAN DO ALL THINGS when you are walking by the SPIRIT, when you are walking in FAITH, when you TRANSCEND the metaphysical world, and when you overcome the LAWS of MATERIALISM and take your rightful place as a “Spirit Being”. Oh yeah!
