Because, you know, I was not aware of that....
But you are not applying this truth to Genesis, though.
You said:
You mean apart from the whole talking serpent bit and the fact that the sun was not even made until the third supposedly "literal day". Plus God walked in the garden but was not incarnate until Christ. Then of course there are the mountains of evidence for a 4.5 billion year old earth.
Sorry, no, Genesis is a poetic description of the world and of how rebellion against God is the nature of sin.
God does miracles. It is a fact of the Bible. Jesus (God) did many miracles, too. Does that mean we write off the ministry of Jesus as being poetic because He did miracles? No. God can create light without the use of the sun. In Revelation there will be no sun because He will be the light thereof (See Revelation 21:23).
As for God walking:
Moses was covered by God's hand and He only revealed His back parts.
17 "And the Lord said unto Moses, I will do this thing also that thou hast spoken: for thou hast found grace in my sight, and I know thee by name.
18 And he said, I beseech thee, shew me thy glory.
19 And he said, I will make all my goodness pass before thee, and I will proclaim the name of the Lord before thee; and will be gracious to whom I will be gracious, and will shew mercy on whom I will shew mercy.
20 And he said, Thou canst not see my face: for there shall no man see me, and live.
21 And the Lord said, Behold, there is a place by me, and thou shalt stand upon a rock:
22 And it shall come to pass, while my glory passeth by, that I will put thee in a clift of the rock, and will cover thee with my hand while I pass by:
23 And I will take away mine hand, and thou shalt see my back parts: but my face shall not be seen." (Exodus 33:17-23).
In other words, God created man in His image (See Genesis 1:27).
As for a talking serpent:
This is not the first time the Bible refers to a talking animal.
There was a donkey that talked in Scripture (See Numbers 22:28).
Does that mean the story of Balaam is allegorical, too?
Surely not.
Also, Jesus encountered men who were possessed. It is not far fetched to say that the devil possessed the serpent so as to speak through it. In fact, Jesus cast a bunch of demons that were possessing a man into a herd of swine (pigs).
As for the so called evidence that the Earth is billions of years old:
Yeah, I just do not see that at all. The scientific evidence suggests the Earth is young and not old. The rotation of the Earth, the amount of life on the Earth (and it's fossils), blood found in a dinosaur bone, sea shells on tops of the highest mountains, etc.
Take for example the drifting moon.
The moon is going around the earth. As the moon goes around the earth, the moon is gradually getting farther away. We are slowly losing the moon. It is only a couple inches a year, no big deal. But the moon is getting farther and farther from the earth every year. Since the moon is getting farther from the earth every year, that means that it used to be closer. Well, if you bring the moon back in closer, you create a problem. The moon is what causes the tides. Most places don’t have to worry about the tides. However, if the moon was closer, the tides would be higher. There is a law in physics called the inverse square law, if you half the distance, you quadruple the attraction. A couple of billion years ago, the moon would have been in so close that the tides would be so high, that it would drown everything on earth twice a day. It just cannot be billions of years old.
Jesus referred to the beginning as the time of Adam and Eve.
"But from the beginning of the creation God made them male and female." (Mark 10:6).
In fact, the genealogy of Jesus Christ goes all the way back to Adam and Eve.
23 "And Jesus himself began to be about thirty years of age, being (as was supposed) the son of Joseph, which was the son of Heli,
24 Which was the son of Matthat, which was the son of Levi, which was the son of Melchi, which was the son of Janna, which was the son of Joseph,

27 Which was the son of Joanna, which was the son of Rhesa, which was the son of Zorobabel, which was the son of Salathiel, which was the son of Neri,

33 Which was the son of Aminadab, which was the son of Aram, which was the son of Esrom, which was the son of Phares, which was the son of Juda,
34 Which was the son of Jacob, which was the son of Isaac, which was the son of Abraham, which was the son of Thara, which was the son of Nachor,
35 Which was the son of Saruch, which was the son of Ragau, which was the son of Phalec, which was the son of Heber, which was the son of Sala,
36 Which was the son of Cainan, which was the son of Arphaxad, which was the son of Sem, which was the son of Noe, which was the son of Lamech,
37 Which was the son of Mathusala, which was the son of Enoch, which was the son of Jared, which was the son of Maleleel, which was the son of Cainan,
38 Which was the son of Enos, which was the son of Seth, which was the son of Adam, which was the son of God." (Luke 3:23-38).
