I say the astronaut because he can do everything the caveman can plus things he can't. Don't go all brute strength argument on me because astronauts are no pansys. They can't afford to be spineless weaklings because if the screw up in the tiniest way they're dead, the crew is toast, and a billion dollar piece of equipment goes up in flames. Also, if the caveman is just fighting with caveman stuff the astronaut can use advanced weapons with super alloys and stuff. Say the caveman does go after him with the club, big deal. It'll take a while before even the best wooden club goes through a solid gold helmet. Meanwhile, the astronaut whoops the caveman's arse with a NASA Brand(tm) Titanium Mace. Oh, you have a sharp piece of hickory? Say hello to the Stihl Caveman Splatterer.
