We are called Earth. "Blue Planet" is a nickname for Earth, since our planet comprises primarily of water.

Because its mostly water.... water is blue
That's because it looks mainly blue, from space. With the clouds it looks like a blue marble.The Earth is called the "blue planet" because the surface is composed mostly of water. Over 70 % of the Earth's surface is water.Water looks blue from space mainly because it reflects the blue atmosphere.However, the full explanation is quite complicated.(A clear sky in daylight looks blue from the Earth's surface, because of the way white light is scattered by the air molecules.)
Earth's name is Earth. The Roman name for Earth was Terra, the Greek on Gaia. However, modern science, and virtually everything else, refers to Earth as "Earth."

Earth is the "blue planet" because of the blue oceans. Oceans cover 75% of the Earth's surface.
Earth is known as the blue planet because of its extensive oceans that give it a predominantly blue appearance when viewed from space. The reflection of sunlight off the oceans contributes to its blueness.
The Earth is Blue or the bio planet. The Earth is known as Blue planet because most of its surface is covered with water.
