When did God give humans permission to eat meat?

After Noah and his family came out of the Ark, God gave mankind permission to kill and eat animals. This was a new permission never given before, marking a different set of circumstances. At that time, God also established human government to restrain murder and crime.

Les explains that when Noah, his three sons, and their wives came off the Ark, all circumstances were totally different than before. God then gave mankind permission to kill and eat the flesh of animals—a permission they never had before. Along with this, God established human government to restrain murder and crime. This marked a whole different set of circumstances, later followed by God calling Abraham and eventually giving Israel the Law.

When did God first allow people to eat meat?

Scripture indicates that God first allowed people to eat meat probably after the flood, when He instructed Noah that he could kill and eat the meat of animals. Before sin and the curse, neither mankind nor the animal kingdom ate meat.
