The miracles and the resurrection are the core elements of the story, it is to miss the point to suggest that these are exaggerated stories so otherwise historical. The point is that this Son of God came down to earth for the purpose of committing miracles and to resurrect from the dead in order to redeem mankind.
Can you just admit that you have no idea what is being told in the Gospels? That would go a long way.
As for exaggerations, many of the miracles can be seen as just that. If one would look at India and other Southeastern Asia areas, you would see that there are still those who believe that gods or sons of gods are walking on earth and performing miracles. One of the famous so called miracles, that many are familiar with, is the act of having a rope rise into the sky, a boy quickly climbing up it, the miracle worker chasing up it after the boy with a sword, after they both disappear in the clouds, body parts rain down, the man comes down, and the boy is miraculously healed, and that is the effect. Of course, this never happens, it is a trick that has been greatly exaggerated. Yet, there is still some basis behind the effect, and we know that some claim to have witnessed just that.
Even in modern times, we see such exaggerations. Houdini is a great example. Some claimed he could dematerialize and that is how he was able to escape any restraint. Of course, that is a myth, an exaggeration, yet we can't simple rule out some idea behind it.
The fact that myth and exaggerations can find themselves into even modern accounts, shows that we have no reason to simply dismiss the Gospels on the basis that they have exaggerations and myths. Especially when we can see similar exaggerations in modern accounts.
