“This was made up due to the “Emaculate Conception” catholic doctrine which states that Mary was without sin, so they had to come up with the ascension because if she was without sin then she never would have died, the ascension is actually a relatively recent doctrine even.”

Nonsense. The Tradition is Eastern Christian, has nothing to do with the Latin notion of the Immaculate Conception and has been a pious belief of virtually universal acceptance in The Church since at least the 5th century.

It's not nonsense it's the truth.

In the Eastern Church, the dormition ("falling asleep") of Mary began to be commemorated in the 6th century. The observance gradually spread to the West, where it became known as the feast of the Assumption. By the 13th century most Catholic theologians accepted the belief of the Assumption. However this doctrine did not become an article of faith until recent times, when Pope Pius XII declared it a dogma of the Catholic faith: “The Immaculate Mother of God, the ever Virgin Mary, having completed the course of her earthly life, was assumed body and soul into heavenly glory” (Munificentissimus Deus, Pope Pius XII, 1950).
