You do realise every living thing, eg. grass, is made from protein?
Don't they teach science in school these days?
Why are cows so big if they are herbivores?

They need larger stomachs so they can 1) Fit the volume in that they require to nutrition and 2) Actually digest grass, which is pretty difficult to do.
The big stomach required a big beast to carry it. The only reason we're able to walk upright is because our diet evolved to include eating other animals, giving us lots of nutrition from a small volume of food and allowing us to walk upright with our small stomach, leaving our hands free to take over the world.

Carbon dioxide, not sunlight!
People need to watch the Inside Natures Giants series. Specifically the episode about the Hippo.
They explain in there why they are so large despite eating only greens. Interesting series in general, especially the eps about the Great White, one of the whales, the elephant and a few others.

In male prisons, there is usually plenty of scope to ingest protein.

Because God made them that way so we can eat them and become big and strong. Checkmate atheists.

Your questions was "why don't humans eat grass". That was and still is a stupid question.
If you wanted to ask "why aren't humans herbivores" then why not phrase it that way? As a human would need to eat far more than grass or leaves to survive, they'd still need a digestible form of protein such as nuts or pulses. And that is also far more worthy of interesting debate than why not eat grass.
I'd actually say your entire OP is phrased quite childishly for someone who obviously knows the background and wants to have an interesting debate. You are allowed to start threads more informatively you know

There's a great episode of Through The Wormhole on this, pretty much points out that should Aliens successfully find us and get here, they'd probably eat us!
The amount of grass needed, per day, to power a sheep brain.

"to power" a brain, say what? Where did that come from, Brainiac or something?
Any science programme that has to explain the human brain in terms of a battery probably isn't very scientific.

Yeah but I was using Cows and grass as an example obviously we can't just eat grass.
Can't be true:

The first animal on earth didn't have any meat to eat so it has to start somewhere. They got all their minerals from a plant which was enough to evolve, then another animal ate that animal and stole it's body which was made of plants, so that carnivore is just lazy.

Development of intelligence is more linked with social structure, animals that live in groups and are highly sociable tend to demonstrate a higher level of intelligence and faster evolutionary development of intelligence than asocial animals, because living in such an environment requires high levels of intelligence to be successful reproductively.
