You are misunderstanding what I wrote. I'm aware that setting nukes off over the ocean won't end all life in earth. I never said that tho and you might have me mixed up with someone else. I said that it will end life as we know it and it absolutely will, setting nukes off over cities will cause radioactive fallout, as well as destroy power grids, the internet infrastructure. It will poison the water. You have to also remember that it will short out the hundreds of nuclear power plants potentially leading to meltdowns, unless they are fail safe designs. I don't think most plants are designed to withstand an emp. Either way a nuclear war would likely mean a reset for human civilization. If you don't believe this then I'm not going to waste my time trying to convince you otherwise.
