Amazon Stonehenge

i was quite excited this morning when i was reading zaobao.

it is said tat there is a astrological observatory found in Amazon, Brazil.

Like Stonehenge, its made of stones in weird positions. The researchers conclude tat this 'formation' is actually an observatory.

I began wondering... E world is full of werid things which we, the modern ppl, dont understand the use and purpose of such sightings...
