The Holy Grail and Creation

In the papers recently it is reported that a 14th century church's stonework was chipped no doubt by hunters looking for the Holy Grail. They were trying to remove blocks of stone to see if there was a void hiding the relic.

Now the Holy Grail is the chalice used in the last supper, and received Christ's blood. It did once exist and might still be hidden somewhere, surely?
I would love to know is where the Grail is and what is in the artifact called 'The Arc of Covenant'?

But, surely you will say, if I was a true believer I should have the faith to understand?
I mean after all there are some questions in life that do remain a mystery.
I believe we were made and the World was made for us to inhabit.
I believe in the 'Creation' but not necessarily starting with Adam and Eve.
I think after 'Creation' we were then allowed to 'evolve' into the form life is now.

So there you are. I'm having it both ways!
