Bill and invoice both refer to a document that is requiring money to be paid for goods or services provided.
In everyday conversation, we usually talk about bills:
The electrical company sends you an electrical bill.
The phone company sends you a phone bill.
After you get treated in a hospital, if you don't have health insurance, you'll have a lot of medical bills to pay.
When talking about a business or professional relationship, then we usually use the word invoice:
A consultant who gave advice to a company would then send the company an invoice (requiring payment for his time).
When a factory sends products to a store, it will also send the store an invoice requiring payment for those products.
Both bills and invoices are sent BEFORE payment. They are requiring the payment to be made. A receipt, on the other hand, is sent AFTER payment. It is the confirmation and proof that the payment was made.
After you buy something in a supermarket, you get a receipt.
After the store pays the factory for the products, the factory will provide a receipt.

We all know cathedrals made of bricks and stone but have you heard of the one made oF well Wind? The answer to that question is the Wind Cathedral of Namibia.

People got curious and wanted to witness the Wind Cathedral for themselves. The place in question is Sossusvlei which literally means dead end marsh. Despite its name it still manages to be one of the topmost tourist attractions of the country. You can find it at the southern part of the oldest desert in the world-the Namib desert in the Namib Naukluft National Park. The place happens to be a photographers paradise. The characteristic feature is the presence of sand dunes exhibiting a myriad range of colours from pink to orange. These dunes are not only vividly coloured but also monstrously high akin to miniaturised version of mountains many of them being 200 meters tall. The highest one of them all is aptly named as the Big Daddy standing at a height of 380 meters. These dunes have been formed over a period of a million years. They are believed to be 60-80 million years old and were formed by the Atlantic Ocean drifts that pushed the sands for eons. The sand dunes display a dynamic behaviour as in they constantly keep changing their contours and shapes due to the shifting of the wind. As a result we have:
