קבלה אויף תהילים 8:5

The ministering angels asked “the Holy One, blessed be He, ‘Master of the universe, ‘what is man, that you are mindful of him? And the son of man, that you visit him?’ (Psalms 8:5). This trouble, why should it come about? He said to them: ‘If so, ‘all sheep, and oxen, and also the beasts of the field’ (Ibid. 8) why were they created? … This is analogous to a king who had a tower filled with all manner of fine things, but he had no guests. What pleasure does the king derive from having filled it? They said before him: ‘Master of the universe, ‘O Lord our Lord, how majestic is your name in all the earth’ (Ibid. 12) – do what pleases you’” (Bereshit Rabbah 8:6-7).
