This is very fascinating! To think that a structure would last more than 100 lifespans is unbelievable. It's massive size and structure is also a very marveling attribute. It is truly amazing what humans can do with the technology we have today. Imagine in about 10,000 years time, we could do even greater things than this! Maybe flying cars will take us to school, maybe houses could get up and move, maybe world hunger could end, the possibilities are endless! This really is breathtaking.
