[PieterCasparzen]

This is fiat creation, ex nihilo. But God doesn't say "let there be grass" He says "let the earth bring forth grass", so some sort of natural process is indicated.

A supernatural process, as the earth in Genesis 1:11-12 does what God commands.

Note that it does not say that God caused seeds to be planted, or that he created seeds which grew into grass plants.

A natural process would be seeds in the ground that were deposited by existing grass plants growing into new grass plants themselves.

If God had only said "let there be grass", that command would not specify that the grass would grow out of the earth, it would have been valid for the grass to grow in midair hovering over the ground, or grow on top of lakes and oceans, but we see that plants grow out of the earth.

His command also expressed the context in which grass grows, and set forth the pattern of procreation of plants:

Genesis 1

"11 And God said, Let the earth bring forth grass, the herb yielding seed, and the fruit tree yielding fruit after his kind, whose seed is in itself, upon the earth: and it was so.

12 And the earth brought forth grass, and herb yielding seed after his kind, and the tree yielding fruit, whose seed was in itself, after his kind: and God saw that it was good."

Thus Genesis answers the question of which came first, seeds or plants: it's very clear that God created the plants, and the plants would produce seeds which would reproduce the plants.

The creation of plants not from seed would definitely not be the natural process we see.

The creation of plants not from seed would definitely not be the natural process we see. Well, of course not, since the process that we see is cyclical. Yet the agent specified is "the earth", with God ordaining or commanding that this should happen. To me it's just very open ended as an explanation. And I should say that I quail at the term "supernatural". To me this invokes witchcraft and ghosts, and I'm loath to think that Natural Creation is founded on such terms.

And let there be light!
