there is SO much information out there if ya sit and search....its over whelming at times to sift thru and find the good stuff buried under tonnes of crap 
It's been said the reason why scientists don't care nor concentrate on our past history, is because they want to hold onto the status quo. It's all good if we find out that T-rex may have had feathers as a juvenile, but human civilization being 20,000-100,000 or more years old, forget looking for those clues and building upon that. Even the most prominant Egyptianologists will not hear that maybe other cultures influenced or were in Egypt prior to the Kings of Old. Even when the Sphinx is said to be 15,000 yrs old, not 10,000 yrs old.
