Passage

Rohan is watching a video of Group Captain Shubhanshu Shukla, the first Indian on the International Space Station. In the video, the astronaut says that from up there, the Earth looks like one big home. He cannot see any borders, states, or different countries. He tells the Prime Minister that we are all just one part of humanity. Rohan wonders why we have maps with so many lines if the Earth looks like one single blue ball from space.

The Earth looks very tiny from high up in space
Smaller details disappear and we only see broad shapes of land and sea

It shows deep love for one's country even when looking at the whole world
