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.

1. This sheds new light on the creation. I had assumed from the previous verses that God created the plants and man on the earth, but it appears from this statement that He created them prior to introducing them to the earth.
2. God created plants for the earth before He caused it to rain on the earth. This suggests He either created them in a state or form that did not require water, or that He had them in water elsewhere and then transported them to the earth.
3. This verse, like a few previous ones, raises interesting questions about the creation process God followed. Not only is it not clear how many individuals were involved, but now it is not clear how it was done or when they occurred. One thing appears fairly certain, however - God did not simply issue a command for plants to begin growing and, blink, there they were.
