Not true: the Amazon Rainforest is known to be at least 55 million years old:

(Also, exactly which pyramids is this referring to?)

Well all of them in South America the vegitation has took over once again but,In 2010, archaeologist Quirino Olivera and his team started digging into the Montegrande hill, and soon discovered what they were excavating wasn’t a hill at all. It was a massive pyramid, built by a forgotten civilization in the Amazon rainforest – and it was over 3,000 years old,so if the Amazon is 55 million years old and the lost civilization came and built pyramids 3000 years ago means we survived because they cut massive amounts of trees down in order to build those pyramids.

I think he's meaning the Mesoamerican pyramids.

Yeah, my first thought was the Mayan pyramids in Mexico and Belize - but then I realised that those pyramids are about 1,000 miles away from the Amazon :P . However, judging from his most recent reply, it seems like he's talking about a pyramid in Peru, on the outskirts of the Amazon Rainforest.

It's true that these pyramids would have required a lot of trees to be cut down: according to this article, the pyramid covers more than two acres of land. I'm guessing they would also have cleared the area around it - so, perhaps the total land area cleared would have been more like 20 acres (that is, ten times the size of the pyramid).

So, how does that compare to the area of the Amazon Rainforest? Well, we all know it's massive - but it's easy to underestimate just how massive. The rainforest currently covers an area of 5.5 million km2 - and, since there are roughly 247 acres in 1km2, this means the forest covers an area of around 1.36 billion acres. Divide that by 20, to get the number of pyramids that would fit into this space - and you get 68 million. So, if you allow 20 acres of land for each pyramid, then you'd need to build 68 million pyramids before you cut down the entire rainforest :P .

In conclusion: this pyramid only takes up a tiny fraction of the Amazon Rainforest, so felling the trees to build it wouldn't have been enough to do any damage to the global ecosystem.

And now, the figures for August 2018 to July 2019 have been released. During that period, 9,762 sq km (3,769 sq miles) of rainforest were destroyed:

If we compare to this table, that's the worst deforestation since 2008, when 12,911 sq km were lost. It's still not as bad as it was in the 1990s and early 2000s, when around 20,000 sq km were routinely lost every year - but, it's still not where we want to be -_- ...
