The first human flight was achieved by the Montgolfier brothers in a hot air balloon in 1783.
Talk about brave! The brothers flew 3,000 feet above Paris for a distance of about 5.6 miles. After 25 minutes, the balloon landed safely outside the city.

#3 There were no roads though, because they had no wheel. So advanced civilization? Not entirely.

Carolyn,
If we used hovercraft instead of wheeled vehicles, we would not have to waste tens of billions every year building and maintaining roads; we would just need a few guardrails here and there to protect landscaping. And no need for spreading salt and brine to melt road ice because the hovercraft would basically treat all surfaces the same, whether lawn or snow or water it would make little difference.
Also, damage from accidents would be negligible, so insurance rates would be minimal.
Not to mention that squashed critters due to tires running over them would be a thing of the past.
So it seems like the Aztecs were ahead of their time.
