Exactly how far back are you looking? 10k BC? 5k BC? 2k BC? 1 BC? To say it makes a big difference would be an understatement.
10k BC and you are looking at the end of the Ice Age, pottery, the rise of the first metallurgy (in the form of copper, mostly), the start of horticulture (but not yet - quite - agriculture), and so forth. Flint axes, spear points, and arrow heads are still common, and semi-nomadic lifestyles are also common. The first cities (towns, really) are soon to rise but have not yet done so, as without true farming / agriculture such a life style is somewhat difficult.
5k BC and you have a solid bronze age on your hands. The first "cities" (towns) are rising, agriculture is blooming, metal has all but replaced stone for many tools and most weapons. Old Kingdom Egypt and Sumer and Akkad are either rising or solidly in place. The first writing has not yet arrived, but it is not all that far off either. Smiths are considered somewhat magical for their ability to mix different metals and come up with "new" metals (alloys) that sometimes have different properties (colors, hardness, etc) from the original metals used.
2k BC and you have Babalon, Middle Kingdom Egypt, the introduction of Iron (although it is still quite rare - mostly located in Anatolia with the Hittites, if I recall correctly). Writting is common amongst the elite and the religious, although not too well known elsewhere. All sorts of huge monuments, etc are being raised (usually for religious reasons). Chariots are in use by now, I am mostly certain. I'm mostly certain they were not in use in 5k BC, although I could be wrong.
1 BC is more advanced yet. Iron is common. Ancient Greece has been around for a few hundred years and has begun to be overshadowed by Rome, Rome itself has recently risen to major prominence but has not yet reached its maximum size, the New Kingdom Egypt is just starting to wane. Iron has all but totally replaced Bronze in many places. If you want a bronze age equivalent location for this period you should look to the ancient celts and germanic peoples - although some of them are starting to pick up iron working from their Roman neighbors.
Really, we need to know more about when your setting exists than just "B.C.". It could be anywhere from paleolithic 'yet to discover fire' to nearly the height of the Roman Empire.
