Cold Steel,
Greatest enemy of miracles is Bible itself. While it reports about miracles such as curing the blind, resurrecting the dead ... it also gives weightier reasons to doubt those reporting because recipients of those miracles do not respond befitting the recipients. None of them came in defense of Jesus while he was falsely being tried in the royal court, nor they came for preaching activity even after Jesus left the stage. Why people come to die for terrorist leaders while Lazarus did not come forward for Jesus? Because as Cofty says they are all myths.
You also said: "Even today there are miraculous healings that take place because of the faith of those being healed."
If you lose one of your legs or hands, why faithhealers of today are unable to cure it? This is because miracles happen "always in the past, in the forgotten history, not in present tense."
