We learn from here the humility of the Holy One, Blessed is He. Since man is in the likeness of the angels, and they would be jealous of him, for this reason, He consulted them.
They were not aware of the way of modesty, to distinguish between good and bad. Even though there had been put in man knowledge to be able to call the animals names, there had not been put in him the drive towards evil.
The Torah begins with an account of the Creation so that if there ever comes a time when the nations of the world accuse the Jewish people of having stolen the Land of Israel, the Jews can respond:
I will make the land [so] desolate- This is [actually] a kindly measure for Israel, for their enemies will not find any satisfaction in their land, for it will be desolate of its inhabitants.
