This is rubbish:

It is theoretically IMPOSSIBLE that a tomb wherein the Mother of God was not only laid to rest, but from where she later rose body and soul into Heaven, to have been completely forgotten.

.
Why is that rubbish? Here's why:
.
The place of burial for Moses is not known. But that he died is contained in Scripture (Deut. 34: 5-7), nor are there any relics of his body to be found anywhere.
.

[5] And Moses the servant of the Lord died there, in the land of Moab, by the commandment of the Lord:
[6] And he buried him in the valley of the land of Moab over against Phogor: and no man hath known of his sepulchre until this present day.
[7] Moses was a hundred and twenty years old when he died: his eye was not dim, neither were his teeth moved.

.
Most of the miracles Our Lord performed are not recorded in Scripture. Does that mean they didn't happen?
.
Even Padre Pio, who died recently ( 1968 ), was known to have worked many miracles every day, while we only have record of a few of them. For him, miracles were as commonplace as everyday life for the rest of us. How then could it have been otherwise for Our Lord?
.
And we don't have ANY record of miracles worked during her lifetime of Our Lady (we have a lot of them attributed to her in our own time but not during her own lifetime).
.
Her miraculous Assumption could easily be seen as the final miracle in a long series of miracles, none of which are recorded, so it's not "theoretically impossible" in any way whatsoever. On the contrary, it's quite reasonable and understandable.  
.
The principle focus of the Apostles was the life and real presence of the Second Person of the Blessed Trinity. It was His life, His passion, His death, His burial and His ascension that was foremost in their minds. And the incomparable humility of the Blessed Virgin Mary would have reasonably had the effect of causing the Apostles to pay attention to her Son rather than to her. She was not all about taking center stage and usurping our attention. It has only been during the passage of history that veneration of her place in the economy of God's salvation has come forward.
.
Perhaps some of the Apostles wanted to keep a memory of Our Lady's miracles and her place of burial but then the Holy Ghost intervened to prohibit them from doing so. Have you considered that possibility? If the Holy Ghost wished to have her sepulchre remembered He would have seen to it that it was. But He did not. Maybe you ought to take it up with the Holy Ghost. But be careful!!
.
It's a Protestant tactic to criticize the Church for veneration of Mary, and here is an admitted sedevacantist claiming that the Church doesn't venerate her sufficiently and must have had it wrong all this time.
.
Maybe you'd like to start your own church and take on fighting all the Protestants as well as the Catholic Church?
.
All you're accomplishing is demonstrating how cutting yourself off from the Pope with your sedevacantism leads you into error by your becoming suspicious and incredulous toward traditional Church doctrine and traditions.

The City of God will give you answers about Our Lady.  

I presume you mean St Augustine.

Since today is the Feast of the Assumption, I thought it would be fitting to set the record straight regarding the story of Mary’s apparent death....

Another genius who cracked code.

Cracked code? What "code" are you referring to? It's docuмented history:  
THE STORY OF MARY'S SUPPOSED DEATH CAME FROM THE MIND OF ONE MAN - A MAN WHO DENIED THE PERPETUAL SINLESSNESS OF MARY.      

Neil Obstat,
Far be it from me to answer the statements of a babbling Freemason. Nevertheless, for the sake of the Catholics who frequent this site, I'll indulge you: Your position regarding the story of Moses' death is irrelevant. Unlike his case, where we were still given ample testimony by the Holy Ghost of the circuмstances involving his death and burial, not one single word was mentioned anywhere regarding Mary's supposed death and burial. No tomb, no story, no evidence whatsoever.
And yet you hold this up as your proof...

Anyone who does not know of the book City of God  by Mary of Agreda (Cuidad De Dios, by Maria de Agreda ), has no business teaching others about Our Blessed Mother. Fools rush in where wise men fear to go. English copies also have the anglicized title of Mystical City of God. It is four volumes about the whole life of the Blessed Mother written in the 1600's. If you want to know about her whole life read the book and come back when you are done.

Well Neil, since we have established that you work for NASA and believe in aliens, it would not be a surprise that you are or have been a freemason.
So for the record, can you please deny that you have ever joined a Masonic lodge? (if you have and repented, please make that clear)
But I do agree with you on the issue at hand. He is talking rubbish. The majority of theologians say she died. hence the papal citation above.
