We may not be gods, but we have certainly shaped the world. We've converted forest and prairie into farmland, changed the course of rivers, reshaped mountains for our own amusement, built structures that dominate local landscapes, and burned so many fuels that we seem to be changing global weather patterns.
It is entirely reasonable to make an effort to better preserve our habitat.
It is hubris-as-a-sin to think that a) we changed it to the worse and b) we are able to change it back.
No, we did not and we can not. There is no single 'climate' also.
All we can do is adapt, but instead we're throwing resources at an altar of a false god so to say.
We can look around us and visibly see changes humans have made to this world. It isn't hard to conjecture that these changes likely have unintended effects.

That's demonstrably untrue though and to be blind to that is to be blind to decades of well-researched climate science.
