No, you dont have any excuse at all...
Ok, so you are saying you cant even use a calculator... putting that aside, just looking at the numbers should have told you it was clearly wrong....
As I understand it, you are saying that the heat is converted to infrared radiation and that energy is radiated into space. Where can I get evidence that such an event is taking place at the same pace as the generation of the heat?
NO! THAT IS NOT WHAT I SAID AT ALL! The numbers I ran were intentionally WORST CASE- I DIDNT INCLUDE HEAT LOSS FROM THE EARTH AT ALL. I did this intentionally to show that even if you make unrealistic assumptions in order to maximize the effect you claim, you STILL get a negligeable effect!!!
I set an upper bound and showed it was ridiculously small... the real effect MUST be less than what I calculated- MUCH less.
What the hell makes it so difficult for you to understand?!
