*shrugs* Not a hunter huh? Never messed with snares or traps? The principles remain the same, just extrapolated to larger sizes. I don't see hunting any animal as being particularly daunting Just a matter of the right trap and presentation to turn the odds decidedly in your favor... Then the proper tool to kill it.
I don't think running up and killing it with spears (as usually depicted) was necessarily all there was to that story.
I had read as a child that some of the western indian tribes would herd buffalo to a cliff and run them over it.
