recorded time
Allegedly, ancient Chinese SEA-GOING vessels were built for exploring the earth; consequently they were built larger. The Chinese may have known that the earth was far vaster than their European counterparts. Recall, if you will, that Europeans believed that the world was FLAT and not round! chinese ships were much heavier

Yes, there are. A lot of them too.Chicago has had many public transportation and infrastructure challenges since it was founded, and has often sought underground tunnels as a means of solving these issues.As a result, there is indeed a pretty vast underground network of tunnels in the city of Chicago.Some of the projects that Chicago has well documented are:Water Tunnels (1850s)River Tunnels (1869 - 1892)Freight Tunnels (1899 - 1959)Subway Tunnels (1938 - present)These are the projects that are well documented. There were countless other projects that probably were not very well documented, and they too often left their tunnels intact underneath the city.The freight tunnels that were built over a 60 year period from 1899 to 1959 were eventually abandoned and for the most-part, are no longer in use today but they do still exist.There have been many examinations into the life of Chicago's 'hidden city' or 'undercity' because it does indeed seem to be a place that other people have gone to, particularly those of impoverished status, to create their own communities within the already dense and elaborate Chicago city that exists above the Earth's surface.The tunnels are expansive, and they were created for many different reasons. Some are less safe than others as time and erosion take their toll, but even today there are a lot of tunnels under the city of Chicago that no one, save a few that might be part of the communities that survive there, is aware of.It's really a very interesting thing to study.Yes, there really are a lot of tunnels underneath Chicago. A lot of them.
The Chinese would be digging to the US. Actually we would all be digging to the center of the earth.
an earth worm lives in the soft, damp soil underground digging tunnels like a mole. roundworms are parasites that live inside your body and can kill you
