Ge 1:24  Then God said, "Let the earth bring forth the living creature according to its kind: cattle and creeping thing and beast of the earth, each according to its kind"; and it was so.

25 And God made the beast of the earth according to its kind, cattle according to its kind, and everything that creeps on the earth according to its kind. And God saw that it was good.

Again, the purpose of Moses was to show Israel that the things that the pagans around them worshiped, the cattle, the creeping animals and the beast of the earth are God's creation.

They are not to be worshiped as the Egyptians did back in Egypt.
