ancient men had different perceptions similar to those insects still have...inborn knowledge and collective mind was present in humans too at the beginning of time when languages were not developed yet but we were master builders and master astronomers able to create fluorescent colonies of humans...we have lost those perceptions and acquired others to be able to learn communicate and pass on knowledge

Always love how everything that can't explain are tombs. Why is it there not homes or shops? Why are they always tombs? If there all tombs where did the people live before they died know make a city like this just for the dead and not have a place they love
