Christianity didn't offer much different except essentially for a more encompassing buffer between man and his personal spiritual agency (which, granted, is something that is very necessary to small people as being responsible for their actions and the consequences thereof terrifies the masses)
They both offered spiritual hygiene, although in different ways, but ultimately led to a smiliar place of spiritual fulfilment. I find it difficult to believe that there was no element of premeditation in presenting Jesus to pagans in a way that made him fit their ideals, but sure, we can let this one slide and call it an organic synthesis of ideas post-fact. This one cannot be denied as ultimately, there are a whole lot of pagan themes and traditional appropriations in european christianity. You simply cannot just sweep in and replace everything, it's always a give and take.
Separating the physical from the metaphysical is dangerous grounds, as it leads to dualism and death-cult tier rejections of the material. One must understand that man isn't flesh and man isn't spirit. Man is both. Therefore, both aspects are important and must be treated as such.
I find it silly to sacrifice the material for a promise of the immaterial.
The ascetic is as misguided as the hedonist (unless it is their place to be such)

My idea of man's destiny and why we are here? Is it not enough to know that we are here and to live? When/if your time comes, you will do what must be done and fulfil your role if you have one, if there is no role then you make of it what you will. It's really not that deep, and seeking meaning because agency is scary is the exact reason we have dogmatic religions. It really keeps the grain farmers from going insane/depressed.
