There is no factual evidence to support it anywhere.
It would be like believing in a carpenters son who walks on water and raises the dead.
Purely a matter of personal belief supported by no physical evidence !

Heinrich Schliemann went hunting for ancient Troy believing that everything that Homer said in his Iliad is true. He did not have any relics or physical evidence except a fictional tale from an ancient greek poet. Many archeological discoveries today do confirm ancient legends.
Unfortunatelly the science do not have always physical evidence of the phenomena it studies. In many cases the nature of the phenomenon is revealed by indirect data, but to get back to the topic...
I did not say that Lemuria existed, I said it is possible that it existed, and there is noting in the plate tectonic theory that will restrict formation and destruction of a chain of volcanic islands.
My personal belief is that this place existed long time ago on our planet, but that's another story...
