Genesis 2:1 says, Thus the heavens and the earth were finished, and all the host of them.  Creation was complete.  We can either accept that all things are possible with God or not.  If we accept that God created everything from nothing, then we should have no problem accepting what He said the time frame was.  Verse two states, And on the seventh day God ended his work which he had made; and he rested on the seventh day from all his work which he had made.  We are told that God rested on the seventh day.  This was not because He was tired, but because He was finished.  We are told that we are to set aside the seventh day, or now the first day, or Lord's Day, for God.  Verse three declares, And God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made.  As just stated above, God blessed and sanctified the seventh day.  After Christ's burial and resurrection on Sunday, the first day of the week, I don't believe that we are wrong to set it aside for God instead of the seventh, or Saturday.  The Jewish people still celebrate the Sabboth, or seventh day, but they do not acknowledge Jesus as the Messiah.  Verse four states, These are the generations of the heavens and of the earth when they were created, in the day that the LORD God made the earth and the heavens,  I believe that this is referring to what was stated in chapter one, and that generations means beginnings.  Verse five adds, And every plant of the field before it was in the earth, and every herb of the field before it grew: for the LORD God had not caused it to rain upon the earth, and there was not a man to till the ground.  The plants were growing, but there was yet to be rain, because God had yet to cause the rain to come, nor was there anyone to till the ground.  Matthew Henry points out that this is the first time God is named and that He is the LORD.  Verse six says, But there went up a mist from the earth, and watered the whole face of the ground.  God watered the plants with a mist and sustained them by His power.  Verse seven declares, And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.  We were created out of the dust, or dirt, of the earth, and would have no more value than any plant or animal, except that God breathed His life into us and we became a living soul.  This will always separate mankind from any other form of life on the earth.  We were created in God's image and He breathed life into us giving us a soul.  Verse eight states, And the LORD God planted a garden eastward in Eden; and there he put the man whom he had formed.  God created a perfect place for people to live.  Verse nine adds, And out of the ground made the LORD God to grow every tree that is pleasant to the sight, and good for food; the tree of life also in the midst of the garden, and the tree of knowledge of good and evil.  God planted the trees that looked good and were a source of food, but also the tree of life and the tree of knowledge of good and evil.  Verse ten states, And a river went out of Eden to water the garden; and from thence it was parted, and became into four heads.  A river went out of Eden to water the garden, then it split into four rivers.  Verse eleven says, The name of the first is Pison: that is it which compasseth the whole land of Havilah, where there is gold;  Verse twelve states,  And the gold of that land is good: there is bdellium and the onyx stone.  Verse thirteen adds, And the name of the second river is Gihon: the same is it that compasseth the whole land of Ethiopia.  Then verse fourteen concludes, And the name of the third river is Hiddekel: that is it which goeth toward the east of Assyria. And the fourth river is Euphrates.  I will not attempt to identify these rivers, though many people do.  I believe that the key is to simply accept that God created this garden and these rivers for the benefit of mankind.
