Check Genesis. Even God loved the smell of burning meat!
I am talking about the millions of years being bunk, not about cooking. Figured you’d know that.
And further, man did not eat animals until after the flood. God showed Adam how to make a burnt offering, but they didn’t eat the offering. We know that mankind was to eat the seed-bearing plants of the garden. After the fall of man, God told Adam now he’d have to work hard to grow crops to eat. We further know that mankind was able to eat animals after the flood when God told Noah that now everything that lived on the earth would be meat (in addition to the plants they always could eat).
