there have been a few ice ages in the last several hundred thousand years , and a trace back to the original human may
not be possible using the passed down versions of history and
creation.

because there may be cultures that were wiped out because
of the climatic changes in the areas that they migrated to.

so the only remains of these wiped cultures would be any
bits of pieces they left behind.

and much of those pieces would be under the seas today
because the sea shore would be the warmest places to be
and a better place to be for those who like eating fish.

so the best evidence we have is found in the written history and creation stories that we know about.

there's really no way to tell just how old man is by the
evidence that we do know about.

but the evidence that we do know about points to creation
and not to evolution.

there have been no major changes to species found in that
one species is shown to have become another species ( kind ).

if I had to choose ( without any solid evidence ) I would say
that apes devolved from man possibly due to climatic
changes ( adaption ) during the ice ages what are today
referred to as apes were men left out in the cold while
what is now referred to as modern man went underground to survive.
