When people are spiritually very advanced, will they not accept contemporary human incarnations?

[Smt. Chhanda asked:- In continuation to my earlier question, regarding the sequence of ten incarnations, I would like to know once again that even though people were spiritually very advanced, You had to appear in the form of a Fish, then as Tortoise and so on. Could it not happen just by simply coming as human incarnation as they could have accepted more easily? Their ego and jealousy were minimum then. But now the case is different as ego and jealousy is highest in this Kaliyuga. At Your divine lotus feet always, Chhanda]

Swami replied:- In the Kruta Yuga, God came as a fish and a tortoise not to preach human beings since there was no such necessity to preach people following justice perfectly. The fish came to kill a demon hidden in an ocean. The tortoise came to support the mountain used in churning the sea. Such forms were congenial to the water-phase. The incarnations of Varaaha and Narasimha were also in the same manner who just came to punish demons. The incarnation of Vaamana was in human form since God wanted to ask King Bali for donation of a small bit of land.
