And God said, Behold, I have given you every herb bearing seed, which is upon the face of all the earth, and every tree, in the which is the fruit of a tree yielding seed; to you it shall be for meat
This was before the fall. God clearly sees the ideal diet for humans as a vegan one. Fallen humans might prefer meat
A lot changed after the flood of Noah. People stopped living up to a 1000 years and the climate altered. God tells man this. The earth that then was destroyed by water and the word of God.
1 And God blessed Noah and his sons and said to them, “Be fruitful and multiply and fill the earth. 2 The fear of you and the dread of you shall be upon every beast of the earth and upon every bird of the heavens, upon everything that creeps on the ground and all the fish of the sea. Into your hand they are delivered. 3 Every moving thing that lives shall be food for you. And as I gave you the green plants, I give you everything. 4 But you shall not eat flesh with its life, that is, its blood. 5 And for your lifeblood I will require a reckoning: from every beast I will require it and from man. From his fellow man I will require a reckoning for the life of man.
6 “Whoever sheds the blood of man,
by man shall his blood be shed,
for God made man in his own image.
7 And you,[
a] be fruitful and multiply, increase greatly on the earth and multiply in it.”
For they deliberately overlook this fact, that the heavens existed long ago, and the earth was formed out of
water and through
water by the word of God, and that by means of these the world that then existed was deluged with
water and perished.
