BB says that overwhelmingly the initial elements produced were hydrogen and other exotic forms of plasma and "high energy" materials. As things expanded and cool and this early hydrogen started to coalesce into stars, conditions were more ripe to lead to the creation of heavy elements as a result of stellar fusion.
It's pretty unlikely that all the carbon in the universe today is purely from the big bang. Far more has been cultured in the bellies of dying suns than anything else... so yes, everything in our universe sourced from that protomass, but it's not like everything "sprang out fully formed from Jupiter's leg". It took some time for things to expand, cool, and set the stage for this mid-life phase which allowed for things like carbon and iron and so forth.
Who knows. Perhaps the physical characteristics required to support our level of life are only transient, local phenomena around this little snippet of our spiral arm, again at a high probability against.
