Obviously you never felt the need to wear a batting helmet while
playing
baseball ( which explains a lot - I couldn't resist;)).  A baseball
can
easily kill a full grown man.  A rock of similar weight would fly even
faster being much smaller and thus be even deadlier.

Many people kill large animals without dogs using spears alone ( i.e..
Tutsi
warriors who want to become eligible to marry by killing a lion).  A
few
well placed rocks first makes the whole thing easier.
