Gee - you seem to know an awful lot, for someone with about zero background in science, and who is wrong so often.HokieAl wrote:Mercury has no atmosphere. Same reason the moon is hot as hell in the sun and cold as hell in the dark.
Yes, the thickness of the atmosphere is a factor. But it is NOT the only factor.
Let's see what knowledgeable experts have to say on the subject. We already know what Carl Sagan said decades ago (and he agreed with ME, not you).
So let's see what others say:

As for earth:NASA wrote:Carbon dioxide is a greenhouse gas that traps infrared radiation beneath Venus's thick cloud cover. A runaway greenhouse effect is what makes Venus even hotter than Mercury!

These records of atmospheric carbon dioxide concentration over time are based on studying the gases trapped deep in the Antarctic ice, brought up by drilling "ice cores." The plot indicates that carbon dioxide (CO2) in the atmosphere has correlated very closely with temperature changes over this period buttonbook.jpg (10323 bytes). This is strong evidence that the CO2 greenhouse effect has a significant influence on temperature on the earth.
