Well the answer to that my fellow readers would be as simple as, when a few million years ago about 2.6 to be precise the oceans and sky were blue, these strange cynobacteria formed together to create the great stromatilite. They used photosynthesis like a plant and produced oxygen. The oxygen then filled the atmosphere and the ocean changed blue. The sky reflects the color to the ocean so it was blue to.
These cynobacteria are the cause of oxygen in the earth. Later, the ozone layer was formed from carbon on the very outer part of our planet,s atmosphere. So, now you have heard it from me my explanation to the blue skies and seas from all over the world. It is a true magnificent sight to have such a stupendous world filled with so many wonders.
