You mean that Jesus might have walked on water or turned water into wine? Science says that he can't do that, so the only way that he could do it is deception or a miracle. Believers say that it was a miracle.
A (true) miracle by definition is beyond what's scientifically possible. Another one would be dying on the cross and then coming back to life. Ascending into Heaven. Reviving Lazarus. Curing blindness and leprosy. And a bunch of others:

Believers believe this stuff, and they run countries. I don't see that Poots's beliefs are any worse.
