Well to go ahead and clear this bit up ... power lines don't confirm anything ... The traveler went out and terraformed much if not all of our solar system making it condusive to human life. We then had the golden age where we spread throughout these planets creating huge cities on mars and venus with mercury becoming a 'garden world' as stated directly in the trailers. This is 99% a shot of just outside 'The Academy' on Venus. How do I know this ? Every other image of venus out there uses the same color pallet and design tropes of it being an overgrown jungle, jungle being the key where as earths environments are more temperate in nature from everything we've seen.
