In response to the last part. Nope. Verily, verily, (strong emphesis)I say unto you, He that believeth on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father. We are able to meet and beat anything Jesus did in his short time here. The books of the canon were chosen based on wether the person in question did known miracles. And if their book is there and its not known wether they did they haf to be cosigned by someone that did. Ie timothy. This is why healing, exorsism, signs and wonders are possible and promised to evrey believer. The only prerequisite is mustard seed like faith. K first part. If more were possible wouldnt we see more being created. No one stopped evolution from continuing, assuming evolution were true. And that was a process God created.
