Earth is your 'Holy Grail' people, it fits definition of …

an elusive object or goal that is sought after for its great significance

The Grail comes from word Graal, as it is earliest spelled comes from Old French 'Greal', meaning 'a cup or bowl of earth, wood, or metal'

by every definition earth is grail

Grail - Graal - Greal - most commonly accepted etymology derives it from Latin gradalis or gradale via an earlier form, cratalis, a derivative of CRATOR or cratus.
a derivative of cratis, a name for a type of woven basket applied to a dish brought to the..

table in different stages or services during a meal.

Earth will provide your last supper

In the 15th century english writer John Hardyng invented a fanciful new etymology for Old French san-graal or san-gréal meaning 'Holy Grail',

John was a dick...

what John did was describe or parse Holy Grail as 'sang real', meaning "royal blood".

he misinterpreted Earth for a man made vessel containing the blood of Christ

leading to sang real referring to the Jesus bloodline 💩

furthermore

The Grail is first featured in Perceval, le Conte du Graal (The Story of the Grail) by Chrétien de Troyes
In this incomplete poem dated sometime between 1180 and 1191 the object has not yet acquired the implications of holiness it would have in later works

While dining in the magical abode of the Fisher King, Perceval witnesses a wondrous procession in which youths carry magnificent objects from one chamber to another, passing before him at each course of the meal. First comes a young man carrying a bleeding

lance, then two boys carrying candelabras (fancy candle holders) & finally a beautiful young girl emerges bearing an elaborately decorated Graal, what you say 'Grail'

Chrétien refers to this object not as "The Grail" but as 'a grail' (un graal)..

For Chrétien a Grail was a wide somewhat deep dish or bowl.
Chrétien's Grail held but a single Communion Wafer.
which provided sustenance for the Fisher King's crippled father

that isn't surprising because food sustenance & abundance come from the earth

what is surprising is exactly how lost you have all become

like i said

The Grail comes from word Graal, as it is earliest spelled comes from Old French 'Greal', meaning 'a cup or bowl of earth, wood, or metal'

Ie, Earth - google it up sometime 🥣not 🌏
