How was it scientifically possible for Jesus to come back to life....?

A couple of things come to mind like 1. he wasn't dead. wow, he died awfully fast perhaps he just used some of the skills he learned as a yogi to simulate death and then later revived. 2. He was dead, the body was stolen and people engaged in mass delirium ( like speaking in tongues today) and all claim they saw him to preserve their standing in the community. 3. He was dead and his twin brother took his place ( yes, the bible makes it clear he had a twin brother, if you don't buy it you aren't accepting the written word, you are accepting dogma.) 4, someone else was crucified in his place - the twin, judas, some unknown dude. 5. The spiritual part of him fled before the body died ( my lord why have you forsaken me) and only a spiritual manifestation returned. etc, etc, etc. You see, via 5, that I am not rejecting any religious possibility at all - just yours.
