Milk was not invented as milk is a natural product that is produced by mammals including, cows, goats, sheep and even humans.
Milk that is commonly consumed is produced by cows that have the milk pumped out of their nipples through milking machines.
The consumption of milk by humans dates as far back to the Neolithic Revolution which was around 8000 BCE.
Milk is a substance that is naturally produced by mammals including humans to nourish their young or babies.
Milk comes out of the breast from mammals such as cows, goats, sheep and even humans.
Mothers naturally make the milk through hormones in their bodies which is then expressed out of the nipples.
Humans create breast milk that is fed to the mothers babies just like cows and other animals create breast milk including cats and dogs.
The milk from cows is also used to feed the baby cows as well although we commonly drink cows breast milk.
Cows breast milk was not ever actually meant for humans although we drink it anyway and it's safe for human consumption and actually also very healthy for humans.
Drinking milk can help to keep humans healthy and strong and even be good for growth and bone health.
