Gen 2:5
When no bush of the field was yet in the land and no small plant of the field had yet sprung up--for the LORD God had not caused it to rain on the land, and there was no man to work the ground.
Look at the reason no plant had grown, the ground was dry and there wasn't a man to work the ground. How does this fit the creation of plants on day three which grew without a man being created for another three days? In Genesis 1, it wasn't that plants hadn't grown because there was no rain, the ground had been deep underwater that very morning and the reason plants did not grow between God creating the land in Gen 1:9 and plants in Gen 1:11 is that there weren't any seeds and there wasn't enough time anyway. Not as we read in Genesis 2, that there hadn't been rain and there was no gardener.
But an even bigger problem is when God created beasts and birds. In Genesis 1 the birds are created on day 5 and the beasts on day 6 before God created man and woman. In Genesis 2, God created
man first, then the beasts and the birds, and then God makes the woman.
Genesis 1: plants, birds, beasts, then man and woman
Genesis 2: man, plants, beasts and birds, then woman
