I was looking through some old vacation pictures and came across this one. It sure gives a perspective on how big these trees are.
Central, north, and south America have been home to humanity for tens of thousands of years. Did you think they all just lived in mud huts and worshiped the sun?
The Amazon rainforest is less than 1000 years old. We know that because we can find 1000 year old human ruins built UNDER the rainforest. Did you think the first settlers to reach south America just lied about the cities and people's they found?
(Edit: actually 2k years back is the start of the forest. It really took off after people left and the farmland went wild)
