Kabbalah for Numbers 27:8

Rabbi Yehuda was walking on the way with Rabbi Aba, and asked him: There is one thing I want to ask. Since the Holy Blessed One knew that the Human would sin against God, and that God would have to decree the Human's death, why did God create him? Behold, Torah existed 2,000 years before the creation of the world - but in the Torah it is written "when a human dies in a tent" (Numbers 19:14), [and also] "when a person dies" (Numbers 27:8), "and he died", "and Ploni lived and died". Why did the Holy Blessed One want from humans in this world, if one studies Torah day and night, one dies; and if one does not study Torah at all one dies? All have the same path. A person is separated from that world, as it is written "[the same fate is in store for all...] the good [person] and the sinner"(Ecclesiastes 9:2).
