Then why would you consider not having sufficient evidence why someone doesn't accept all those things to be unquestionably true as defined "an excuse"? Again, this is the reason (not excuse) for not
knowing. The reason (still not excuse) for not
believing is simply a lack of faith, exactly the same reason you don't believe in Zeus or Shiva.
Nothing here has
literally "come back from the dead" though. There are all sorts of creatures which are capable of surviving in various extreme environments or situations but the point is that they survive. At no point are they clinically dead only to change back to clinically alive. And regardless, if we're talking about defined natural processes, none of it would be literally miraculous by definition (though people might use the word casually to mean unexpected, impressive or surprising).
Also, even if some species were demonstrated to have a
natural ability to somehow "come back from the dead", it still wouldn't relate to the Biblical story of Jesus
supernaturally "coming back from the dead". If anything, the discovery of any living creature being able to actually "come back from the dead" would weaken the significance of the Biblical story. Isn't the whole point that the only reason Jesus could do that was because of his unique power as the son of God? It wouldn't be as special if some random insects could do the same thing (and without making a big drama about it
).
