This shows that God was there, in the plural - the Father, Son, & Holy Ghost [the spirit moving upon the face of the waters]. That in itself is amazing, even more so when you consider that the Son was present at the creation, seeing that it was good, even knowing that the creation, and later redemption, of man would mean his own torture, suffering, and death. God was there in paradise, with His holy & perfect Son, and still chose to create man and give him dominion over the earth, knowing what troubles we would cause in our disobedience to Him.

Genesis 1:26
