Well thing is, the Arabians were simply working off what they got from the Greeks and the Romans. Of course there is no proof that the Romans had
microscopes and the lot, but that doesn't explain why, in the first century BC, Marcus Terentius Varro is quoted as saying:
"When building a house or farm especial care should be taken to place it at the foot of a wooded hill where it is exposed to health-giving winds.
Care should be taken where there are swamps in the neighbourhood, because certain tiny creatures which cannot be seen by the eyes breed there. These
float through the air and enter the body by the mouth and nose and cause serious disease." Marcus Varro.
One must wonder how they knew this without a microscope. I'm not saying they had one, but clearly the knowledge was gained some how.
I’d say the Chinese were there in 1500 years before if you mean city organization, roads, fortifications and canals however we may be defining
'infrastructure' differently
I define infrastructure as the easy by which a citizen may travel, live, and do business within their own nation. The Chinese clearly had practical
knowledge. One does not simply build a wall that can be seen from space without engineering knowledge. The Dougong was quite a genius little creation
However, China did not have 200 year old domes that have survived earthquake, the fall of civilization, and many other woes.
Probably not as the Chinese didn’t have it until centuries after Rome had fallen
I'm not so sure. There's a great deal of ancient stories involving entities that must have been fueled by some sort of explosive. However this is
speculation. For without written proof, how can we know.
Again, in many cases inventions have existed for eons before they were "invented", people simply did not know that they could be used that way. One
way to know this for sure is when something that's pretty complex just happens to pop into history. Chances are it was around for a while, just no
body thought to use it that way.
