Now I'm all confused....
I had a stand in the Cavemen vs. Astronauts...but just modern man doesn't work for me.
I figure...regular Gladiator Arena and I guess it doesn't matter men or women...but I'm all for the cavemen..weapons or not. I mean, in all reality...what kind of "battle training" do astronauts get? Sure, maybe they can make new air filters from scrap while orbiting the moon, but I doubt they're trained in hand to hand combat. There's really no normal reason for an astronaut to have a gun. So, if we just put them in there with the things they use in daily life...what do we have?
The astronauts have what? Calculators and maybe some oxygen tanks? And the cavemen would have clubs and sharp rocks and sticks and are used to battling for their lives.
The whole situation changes if we just say, "Modern Man". I mean, that opens it up to a LOT! Bill Gates, Donald Trump, Hulk Hogan, my drunken cousin in Texas who carries multiple shotguns in the back of his truck for aid in random traffic infractions.....the options are just too vast.
(By the way, I think my cousin could take the cavemen...in fact I think they speak the same language.)
