Genesis 1
29 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. 30 And to every beast of the earth, and to every fowl of the air, and to every thing that creepeth upon the earth, wherein there is life , I have given every green herb for meat: and it was so.
So was Adam and Eve vegan? It says the plants where his "meat " and "herbs " "meat " for animals. No where does it say GOD say they can eat the animals. Thus why Adam and Eve had to relay on the Garden. When GOD casts them out says they will work the ground for food not slaughter animals.
