(7,670 posts)around, due to evolution. Yes life on Earth would have difficulty surviving on planets with different environmental conditions, because they evolved on Earth.
But life on other planets, that evolved there? It really depends, as far as we know, from life on Earth, it is very robust(examples extremophiles). Apparently the bare minimum to have life is liquid water, a source of energy, and enough variety in elements to allow complex organic chemistry.
This would allow for unicellular and simplistic multicellular life, no problem. What may be required for sapience and civilization would most likely be a planet with a stable atmosphere that's thick enough to protect from most solar and cosmic radiation, a magnetosphere, and stability in orbits that are roughly in the Goldilocks zone to allow liquid water on the surface. Such a planet could be outright hostile to life on Earth, and yet be "finely tuned" for life evolved on it.
Also a note, the neurons in your brain aren't random, that evolved into sapience because it gave human beings as a species a competitive advantage in surviving over other predators and prey.
