Genesis 1:11-12 God created plants.
Genesis 1:20-25 God creats animals.
Genesis 1:27 God created man.
Genesis 1 Plants were created first, then animals, then man.
Genesis 2:7-8 God creats man from dust and puts him in Eden
Genesis 2:9 God makes plants grow
Genesis 2:19 God creates animals
Genesis 2 Man first, then plants, then animals.
Genesis 2:5
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 already there before He created man. Do you see any man created before this verse? It specifically says there was no man there, but the plants were there. In Genesis 2:7 we see God creating man:
Genesis 2:7 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
So, no, the plants were not there before man. What we see is that God, after creating all of the plants, specifically "planted" the Garden of Eden:
Genesis 2:8 And the LORD God planted a garden eastward in Eden; and there he put the man whom he had formed.
The trees that are growing are the trees in the Garden of Eden as we see in the next verse:
Genesis 2:9 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.
We see the same thing happening in Genesis 2:19
Genesis 2:19 And out of the ground the LORD God formed every beast of the field, and every fowl of the air; and brought them unto Adam to see what he would call them: and whatsoever Adam called every living creature, that was the name thereof.
The animals, as the plants, are created in the context of the garden. So here is the true timeline:
Genesis 1:11-12 God created plants.
Genesis 1:20-25 God creates animals.
Genesis 1:27 God created man.
Genesis 2:5 Plants were already there
Genesis 2:7-8 God creates man from dust and puts him in Eden
Genesis 2:9 God makes plants grow (in Eden)
Genesis 2:19 God creates animals (in Eden for Adam to name)
Plants, animals, man..and then plants and animals in Eden
