There are multiple aspects to the phenomenon of resurrection:
1) Miraculous healing
2) Reunification of a soul with a perfected body, at the end-times: Judaism, Christianity, and Islam all have variants of this concept. This is intertwined with the belief in the immortal soul. Eventually, the soul will be re-united with the body, though the new body will also be eternal, and will be healed of any infirmities. For this reason, many sects of the Abrahamic religions prohibit cremation, and have explicit rules for how bodies of the deceased are to be handled.
3) Occult resurrection: zombies, vampires, re-animated mummies, and other undead.
1) The testimony of eyewitnesses is notoriously unreliable. There have been no verified claims of resurrection in modern times, which casts further doubt on the veracity of the accounts of resurrection in the Old and New Testaments.
2) No one knows what happens when we die, though some posit that we have some sort of spiritual essence that can survive the death of the body. (This concept is discussed further here.) There is no evidence to indicate that there will be a paradisiacal Heaven and Earth recreated after the world ends, and there are numerous physical and logistical issues that arise, indicating that such a scheme is incompatible with physics as we know it. Granted that physics, like all sciences, is subject to challenge and change, however, the appropriate evidence has not, as yet, been provided.
3) Despite the popularity of undead creatures in art and culture, there is no reason to think they have any correspondence with reality. Some scientists have provided explanations for how some legends of the undead arose – e.g. the disease of porphyria has been suggested as an explanation for vampire-related folklore (http://en.wikipedia.org/wiki/Porphyria#Vampires_and_werewolves), and various drug cocktails are said to be able to produce a death-like trance, followed by re-animation (http://en.wikipedia.org/wiki/Zombie#Zombies_in_Voodoo); however, these theories have so for not been proven.
All resurrections require that the human soul be able to survive independently of a physical brain and body. However, the overwhelming scientific evidence is that this would be impossible – indeed, damage to the brain starts within just a few minutes after the death of the body, and after a few minutes the damage is profound and irreversible.
1) The evidence for the resurrection events as described in the Hebrew and Christian scriptures, including the resurrection of Jesus, are in contradiction of the current model of medical knowledge. Much more evidence than has been provided would be required in order for this claim to be acceptable to biologists and physics.
2) There is no evidence that the claim of the resurrection of the body at the end time is anything other than wishful thinking.
3) There is no evidence that accounts of the re-animated “undead” are anything more than stories and folklore.
