The different chronologies:   This has been put together to show how subjective chronologies really are.  Though some of the them maybe really close, even 100 years can change a theory or be used to dismiss a location or the Biblical event.   Just the general terms will be used for sake of space: all figures B.C.   Kitchen:  early bronze  3200 to 2000; middle bronze 2000 to 1500; late bronze 1500 to 1000 approx.
