The Assumption of Mary was unheard of for 400 years after the resurrection.
"This is truly an amazing dogma, yet there is no Scriptural proof for it, and even the Roman Catholic writer Eamon Duffy concedes that, ‘there is, clearly, no historical evidence whatever for it ...’ (Eamon Duffy, What Catholics Believe About Mary (London: Catholic Truth Society, 1989), p. 17). For centuries in the early Church there is complete silence regarding Mary’s end. The first mention of it is by Epiphanius in 377 A.D. and he specifically states that no one knows what actually happened to Mary. He lived near Palestine and if there were, in fact, a tradition in the Church generally believed and taught he would have affirmed it. But he clearly states that ‘her end no one knows.’ These are his words:
But if some think us mistaken, let them search the Scriptures. They will not find Mary’s death; they will not find whether she died or did not die; they will not find whether she was buried or was not buried ... Scripture is absolutely silent [on the end of Mary] ... For my own part, I do not dare to speak, but I keep my own thoughts and I practice silence ... The fact is, Scripture has outstripped the human mind and left [this matter] uncertain ... Did she die, we do not know ... Either the holy Virgin died and was buried ... Or she was killed ... Or she remained alive, since nothing is impossible with God and He can do whatever He desires; for her end no-one knows.’ (Epiphanius, Panarion, Haer. 78.10-11, 23. Cited by juniper Carol, O.F.M. ed., Mariology, Vol. II (Milwaukee: Bruce, 1957), pp. 139-40).
In addition to Epiphanius, there is Jerome who also lived in Palestine and does not report any tradition of an assumption. Isidore of Seville, in the seventh century, echoes Epiphanius by saying that no one has any information at all about Mary’s death. The patristic testimony is therefore non-existent on this subject. Even Roman Catholic historians readily admit this fact:
In these conditions we shall not ask patristic thought—as some theologians still do today under one form or another—to transmit to us, with respect to the Assumption, a truth received as such in the beginning and faithfully communicated to subsequent ages. Such an attitude would not fit the facts...Patristic thought has not, in this instance, played the role of a sheer instrument of transmission’ (Juniper B. Carol, O.F.M., ed., Mariology, Vol. I (Milwaukee: Bruce, 1955), p. 154).
How then did this teaching come to have such prominence in the Church that eventually led it to be declared an issue of dogma in 1950? The first Church father to affirm explicitly the assumption of Mary in the West was Gregory of Tours in 590 A.D. But the basis for his teaching was not the tradition of the Church but his acceptance of an apocryphal Gospel known as the Transitus Beatae Mariae which we first hear of at the end of the fifth century and which was spuriously attributed to Melito of Sardis. There were many versions of this literature which developed over time and which were found throughout the East and West but they all originated from one source. Mariologist, Juniper Carol, gives the following historical summary of the Transitus literature:
An intriguing corpus of literature on the final lot of Mary is formed by the apocryphal Transitus Mariae. The genesis of these accounts is shrouded in history’s mist. They apparently originated before the close of the fifth century, perhaps in Egypt, perhaps in Syria, in consequence of the stimulus given Marian devotion by the definition of the divine Maternity at Ephesus. The period of proliferation is the sixth century. At least a score of Transitus accounts are extant, in Coptic, Greek, Latin, Syriac, Arabic, Ethiopic, and Armenian. Not all are prototypes, for many are simply variations on more ancient models (Juniper Carol, O.F.M. ed., Mariology, Vol. II (Milwaukee: Bruce, 1957), p. 144).
Thus, the Transitus literature is the real source of the teaching of the assumption of Mary and Roman Catholic authorities admit this fact. Juniper Carol, for example, writes: ‘The first express witness in the West to a genuine assumption comes to us in an apocryphal Gospel, the Transitus Beatae Mariae of Pseudo–Melito’ (Juniper Carol, O.F.M. ed., Mariology, Vol. l (Milwaukee: Bruce, 1957), p. 149). Roman Catholic theologian, Ludwig Ott, likewise affirms these facts when he says:
The idea of the bodily assumption of Mary is first expressed in certain transitus–narratives of the fifth and sixth centuries. Even though these are apocryphal they bear witness to the faith of the generation in which they were written despite their legendary clothing. The first Church author to speak of the bodily ascension of Mary, in association with an apocryphal transitus B.M.V., is St. Gregory of Tours’ (Ludwig Ott, Fundamentals of Catholic Dogma (Rockford: Tan, 1974), pp. 209–210).
Juniper Carol explicitly states that the Transitus literature is a complete fabrication which should be rejected by any serious historian:
The account of Pseudo-Melito, like the rest of the Transitus literature, is admittedly valueless as history, as an historical report of Mary’s death and corporeal assumption; under that aspect the historian is justified in dismissing it with a critical distaste (Juniper Carol, O.F.M. ed., Mariology, Vol. l (Milwaukee: Bruce, 1957), p. 150)."

The Assumption of Mary was unheard of for 400 years after the resurrection.
From http://www.ewtn.com/library/answers/aofmary.htm
The Assumption is the oldest feast day of Our Lady, but we don't know how it first came to be celebrated. Its origin is lost in those days when Jerusalem was restored as a sacred city, at the time of the Roman Emperor Constantine (c. 285-337). By then it had been a pagan city for two centuries, ever since Emperor Hadrian (76-138) had leveled it around the year 135 and rebuilt it as in honor of Jupiter.
For 200 years, every memory of Jesus was obliterated from the city, and the sites made holy by His life, death and Resurrection became pagan temples.
After the building of the Church of the Holy Sepulchre in 336, the sacred sites began to be restored and memories of the life of Our Lord began to be celebrated by the people of Jerusalem. One of the memories about his mother centered around the "Tomb of Mary," close to Mount Zion, where the early Christian community had lived.
On the hill itself was the "Place of Dormition," the spot of Mary's "falling asleep," where she had died. The "Tomb of Mary" was where she was buried.
At this time, the "Memory of Mary" was being celebrated. Later it was to become our feast of the Assumption.
For a time, the "Memory of Mary" was marked only in Palestine, but then it was extended by the emperor to all the churches of the East. In the seventh century, it began to be celebrated in Rome under the title of the "Falling Asleep" ("Dormitio") of the Mother of God.
Soon the name was changed to the "Assumption of Mary," since there was more to the feast than her dying. It also proclaimed that she had been taken up, body and soul, into heaven.
That belief was ancient, dating back to the apostles themselves. What was clear from the beginning was that there were no relics of Mary to be venerated, and that an empty tomb stood on the edge of Jerusalem near the site of her death. That location also soon became a place of pilgrimage. (Today, the Benedictine Abbey of the Dormition of Mary stands on the spot.)
At the Council of Chalcedon in 451, when bishops from throughout the Mediterranean world gathered in Constantinople, Emperor Marcian asked the Patriarch of Jerusalem to bring the relics of Mary to Constantinople to be enshrined in the capitol. The patriarch explained to the emperor that there were no relics of Mary in Jerusalem, that "Mary had died in the presence of the apostles; but her tomb, when opened later . . . was found empty and so the apostles concluded that the body was taken up into heaven."
In the eighth century, St. John Damascene was known for giving sermons at the holy places in Jerusalem. At the Tomb of Mary, he expressed the belief of the Church on the meaning of the feast: "Although the body was duly buried, it did not remain in the state of death, neither was it dissolved by decay. . . . You were transferred to your heavenly home, O Lady, Queen and Mother of God in truth."
All the feast days of Mary mark the great mysteries of her life and her part in the work of redemption. The central mystery of her life and person is her divine motherhood, celebrated both at Christmas and a week later (Jan. 1) on the feast of the Solemnity of Mary, Mother of God. The Immaculate Conception (Dec. 8) marks the preparation for that motherhood, so that she had the fullness of grace from the first moment of her existence, completely untouched by sin. Her whole being throbbed with divine life from the very beginning, readying her for the exalted role of mother of the Savior.
The Assumption completes God's work in her since it was not fitting that the flesh that had given life to God himself should ever undergo corruption. The Assumption is God's crowning of His work as Mary ends her earthly life and enters eternity. The feast turns our eyes in that direction, where we will follow when our earthly life is over.
The feast days of the Church are not just the commemoration of historical events; they do not look only to the past. They look to the present and to the future and give us an insight into our own relationship with God. The Assumption looks to eternity and gives us hope that we, too, will follow Our Lady when our life is ended.
The prayer for the feast reads: "All-powerful and ever-living God: You raised the sinless Virgin Mary, mother of your Son, body and soul, to the glory of heaven. May we see heaven as our final goal and come to share her glory."
In 1950, in the Apostolic Constitution , Pope Pius XII proclaimed the Assumption of Mary a dogma of the Catholic Church in these words: "The Immaculate Mother of God, the ever-virgin Mary, having completed the course of her earthly life, was assumed body and soul into heaven."
With that, an ancient belief became Catholic doctrine and the Assumption was declared a truth revealed by God.

Jesus created His Church. The teachings of the Church matter. The teachings of the individual may be irrelevant. Those sho spurn the Church and prefer their own interpretation fall afoul of everything that the teaching ministry of the Apostles, sent by Jesus, are supposed to be doing.
