Is it all that matters to you? For example, if the resurrection and ascension of Jesus was an embellishment to express the gospel community's idea of what must have happened because it should have happened, would that bother you?
Let's look at our sources and apply textual criticism. We have four gospels, which likely represent three independant witnesses. John and Mark are independant; Luke and Matthew dependant on Mark, but having material in common which suggests another source for both (Q-gospel). These three independant sources clearly suggest Jesus to have been resurrected.
We have Josephus' account, which though corrupted, clearly originally referenced Jesus' crucifixion and a claim of resurrection, based on the nature of the work, later reference to James the brother of the Lord, and early mentioning of it in Eusebius and others.
We have Pliny's letters, which also reference such a claim made by Christians.
So on historical-critical grounds, it is quite clear that the Resurrection is not an embellishment, but an essential part of the narrative of the gospels, which were conceived as history by their writers, and this contention is supported by other writings of the period. For the history they are presenting is the core of Christianity, that God became man, suffered, died and was resurrected. So here I don't see the problem.
The barebones is not at issue for essential elements of the faith, like the Resurrection or sonship of Jesus, by the nature of the gospels. This is more for details, like was the demoniac from Gerasa or Gadara, or stories unique to one gospel to ponder over. On these elements, I am not too bothered that their form is not necessarily supported on critical grounds or a narrow veridicality. For they either represent the underlying gist of truth that the writers are presenting or they are true elements in entirety.
It all comes down to how much you trust the writers of the period. The gospels have well supported elements, like Roman Governors or administrative boundaries, that no one doubts. Whether you believe the rest: the writers clearly believe what they wrote, it depends how much you do.
It is similar to how Pliny writes on monopods or Herodotus on the gods' intervention or how histories of Alexander may record him being fathered by Zeus in the form of a snake. We don't discount them on account of these for other elements of history.
We need to decide what elements we trust, even if multiple sources concur thereon. The very claim of Christianity is fantastic, even to its writers. Like so much, it boils down to a matter of faith, but its position is no weaker or stronger than secular history of the period.
