WEAPONS OF DESTRUCTION

WAS THE SPEAR THE FIRST WEAPON INVENTED BY HUMANS? – As I take my characters up into the Northern Mountains with their Guide Pierus leading the way, the question comes up, what kind of clothes will they ideally be wearing? In an internet search, I find a drawing of an Ancient Gael and recognize Pierus the Guide immediately! The man has what appears to be a bear-skin draped around his shoulders and is  carrying a long spear. I’ve not mentioned weaponry in MYTHS yet, but I do believe that a Human going into mountains filled with vicious, wild beasts would quite logically be carrying a weapon with him. And it's logical to me also that,other than a club, a spear would have been the first invention of destruction made by Humans, preceding the bow and arrow.  So,... someone has invented the spear..., I wonder who that was....
