The question mentioned a resemblance to Venus. Due to the significant effects of the small amount of sulphuric acid in Venus's atmosphere, I thought it was worth clarifying that that wasn't a factor.

Added a diagram to help clarify one section. It's been released into the public domain unconditionally - see https://commons.wikimedia.org/wiki/File:Moon_Schematic_Cross_Section.svg - so no licensing issues.

Titan is a moon of Saturn often referred to as an analog to primordial Earth when life had just originated ~4 billion years ago. Earth is probably a cold world with a thick methane nitrogen atmosphere and perhaps a handful of anaerobic unicellular organisms. The surface is obscured by the atmospheric haze, which is seen from space as an orange, fuzzy ball(drawing again on observations of Titan.) | |
