Jesus frequently used fleshly, physical, earthly ideas to get across deep spiritual truths. For instance, he once told a crowd of his disciples that they must eat his flesh and drink his blood if they wanted life. Some of his disciples expressed disgust at such a thought, but Jesus, of course, was not advocating that his disciples perform some cannibalistic ritual upon his corpse. He merely was talking about how the sacrifice of his own flesh and blood was going to provide the basis for granting them everlasting life, provided that they "fed" upon him by exercising faith in his sacrificial death. With that in mind, then, we can better appreciate what Jesus was referring to when he spoke about the temple of his body.
Bologna! You are comparing apples and oranges. One key point you are overlooking is that this was in fufillment to a prophecy quoted in the Old Testament and the key is in the line highlighted in red below. The disciples believed the Scripture (already written down)
Psalms 16:10 For thou wilt not leave my soul in hell; neither wilt thou suffer thine Holy One to see corruption. (His flesh)
John 2:19-22 Jesus answered and said unto them, Destroy this temple, and in three days I will raise it up.Then said the Jews, Forty and six years was this temple in building, and wilt thou rear it up in three days? But he spake of the temple of his body. When therefore he was risen from the dead, his disciples remembered that he had said this unto them; and they believed the scripture, and the word which Jesus had said.
It must also be remembered that every verse in the Bible which deals with the resurrection of the dead, and the Lord particularly, refers exclusively to the human body; i.e., a bodily resuscitation; never a spirit or spiritual resurrection. In fact the word 'resurrection' is never applied to the soul or spirit of man. This is born out in the original Hebrew and Greek.
Beyond this, Jesus specifically prophesied that His resurrection would be bodily; that is, in a glorified form of the body He then possessed. When speaking to the unbelieving Jews, as recorded in the second chapter of John's Gospel, Christ stated "Destroy this temple, and in three days I will raise it up" The Jews, however, thought he was referring to the temple in Jerusalem but the Apostle John clearly declares meaning Jesus had in mind in a clear and concise term: " But he spake of the temple of his body"
The Greek word soma is translated "body" throughout the New Testament, so it is an inescapable fact that Christ was referring to his own physical form - hence a bodily resurrection.
If literal makes sense all other is nonsense.
