Some of these myths/legends do appear to have Christian overtones: Walking on water, healing the sick and etc.

These may be additions to the local legends added by the early Europeans?

"These may be additions to the local legends added by the early Europeans?"

That is very possible. For example, I found the following reference to European influence on the legend of Quetzalcoatl:

"Quetzalcoatl was never depicted as white until after the coming of the Spaniards, and then only in writings done by the Spaniards themselves. (see Readers Digest, Mysteries of the Ancient Americas: The New World before Columbus, 1986, 38)"
