Study of the Ancient Civilisations and the Gods

Why does nobody connect all the evidences of several ancient civilisations and create a collage where all of them could be read and studied together to come to a suitable conclusion? For example Ancient Indian + Sumerian/Egyptian+Greek+Maya+ Inca etc etc.

dear writer
I could not agree more, Mr sitchin has gained popularity among
the internet talk shows who stay on the air having guest on that claim
to be experts, but in fact know nothing about the subjects they discuss.
mr. sitchin has been challenged to debate his theories and what he
calls facts by biblical and ancient language academics he has yet to defend
his opinions.

Hi,

I was wondering were I could find info on upcoming lectures.
It seems I am always behind.
I can't find any list on the web.
