So recently, I got into an argument with one of my friends that lasted close to 3 days and got very heated, all based on a very simple hypothetical question: Who would win in a fight between cavemen and astronauts? My basic argument was that astronauts would win because although both are human, both have fight or flight instincts and astronauts are some of the fittest people on Earth. Also, the caveman, over thousands of years, has evolved into the astronaut. My friend was of the opinion that the sheer force of nature that was prehistoric man could take out an astronaut. So I want to hear from you guys about what you think. Give a reason for what your answer and consider all variations and possibilities of the situations, in all possible environments. Rules: 1. Neither of them starts out with weapons. 2. The fight takes place on Earth 3. You're not allowed to use the words "This is a stupid argument, it could never happen" More rules can be established as we go along Here was the inspiration for the argument: [video=youtube;Oq2V0_20Mv8]http://www.youtube.com/watch?v=Oq2V0_20Mv8[/video] Let me hear it!
