No. You selectively parsed your source.
Note: By promulgating the Bull Munificentissimus Deus, 1 November, 1950, Pope Pius XII declared infallibly that the Assumption of the Blessed Virgin Mary was a dogma of the Catholic Faith. Likewise, the Second Vatican Council taught in the Dogmatic Constitution Lumen Gentium that "the Immaculate Virgin, preserved free from all stain of original sin, was taken up body and soul into heavenly glory, when her earthly life was over, and exalted by the Lord as Queen over all things (n. 59)."
Again, not unlike you past attempts to attack the Blessed Mother and the Catholic faith.
You can deny what the information says but it doesn’t change it. You cannot with 100% certainty say it did happen or it didn’t happen. What you can say with 100% certainty is you don’t know if it happened.
