If humans never were here. would earth be better or worse?

Worse,because the earth would be back to how it was before. pure destruction

Both.

Better because . . .
There wouldn't be as much global warming, pollution, man-made problems, etc. There wouldn't be cities, great wall of china, or roads. The night sky would be a lot darker. Forests would stretch on and on. The planet would be much more healthy and green. Oceans would be full of fish and whales. Many animals including the dodo wouldn't be extinct.

Worse because . . .
We would probably be in an ice age because of no global warming. Earth would start freezing over until, it would be all snow and ice. Since, Humans are the most intelligent creature on earth, there wouldn't be much intelligence.

What could go into the both Better and Worse category . . .
There would be no tools, cars, phones, or any type of technology.

Earth would be better and worse.
