Also, how could the entrance to the garden of eden be garded by swords? Why would it have been invented or created back then?
Another questions from readers that is a total cop out:

Consider another example from the early chapters of Genesis. After Adam and Eve sinned and were expelled from the garden, Jehovah prevented them from returning. How? Genesis 3:24 says: “He drove the man out and posted at the east of the garden of Eden the cherubs and the flaming blade of a sword that was turning itself continually to guard the way to the tree of life.” Notice, “the flaming blade of a sword.” Did God invent swords?
We need not conclude that our loving Creator was the first one to make what we know as swords. Adam and Eve saw turning in front of the angels something that was blazing. What exactly was it? By the time Moses wrote the book of Genesis, swords were well-known and used in warfare. (Genesis 31:26; 34:26; 48:22; Exodus 5:21; 17:13) So Moses’ words “the flaming blade of a sword” enabled his readers to visualize to a degree what existed at the entrance of Eden. The information known in Moses’ day contributed to the understanding of such matters. And the language Moses employed must have been accurate, for Jehovah had it included in the Bible.—2 Timothy 3:16.
