Can a perpetually darkening atmosphere exist and yet still allow life to evolve?

I am creating a science fiction worldbuilding project, in which humanity has colonised distant exoplanets. One such planet is a Venus-like planet in the sense that it has a perpetual cloud cover, although on my world it is dense water-clouds instead of toxic sulphur. Although the surface has extreme pressure, temperatures are still Earth-like, and (maybe) suitable for sentient life to evolve (although no life features eyes as there is no light at sea-level.)

Is this situation realistic, and what would the makeup of the atmosphere have to be to avoid the extreme greenhouse effect and yet allow life to evolve?
