so you're telling me that the >800 F temperature on Venus has nothing to do with its thick carbon dioxide atmosphere, even though Mercury is cooler despite being closer to the sun? wow. It's good we have scientists here to disprove such crazy allegations.
-ahem-
Mercury, despite being much closer to the sun than Venus, is actually alot cooler. This is because Mercury has too thin of an atmosphere to trap heat inside it. Venus, however, has an extremely thick atmosphere, which means there are much more greenhouse gasses in it. This traps much more heat than Mercury does. Venus also rotates slower than Mercury, so one side gets cooked for a while before the other side does.
or, basically, you're dumb and should learn the BASICS of astronomy before making such infantile theories.
ot: damn this is actually pretty concerning
