It's only important--as a matter of The Truth--when a Christian states, "The Christian religion has proved its claims..."
There are any number of things in the Bible that are pretty clearly myths. The Ark (that held two of ALL the animals in the world) and the Flood (that killed ALL the animals on earth, and ALL the people) are merely two examples.
If you are not a believer, ok. I don't bash Druids just because they can't tell me if the lady of the lake really kept the sword for Arthur. I really don't care what other's beliefs are as long as they are not out to kill me.
I don't care what people's beliefs are EITHER...other than when they claim their religion is The Truth, while other religions are myths.
As they say, "Those living in glass Arks should not throw stones." The same would go for Druids...or my church, the "Church of the Cosmic Revelation." (Congregation size, 1. At least that I know about.)
