Long, long ago, there was a very small town in Greece that was so poor that it couldn't even afford a name.
Every citizen in the nameless town were completely blind from the dusty smog of the atmosphere and the rain getting into their eyes.
Before all hope was lost, Theia the Titan goddess of sight and light walked into the town and promised everyone there that they would be able to experience sight for the first time in forever by turning the sky into glass.
However, everyone hated this idea and kicked Theia out of the town.
Theia ran away from the town with eyes full of watery tears from not being respected as a helpful goddess.
Meanwhile in the town, the people are just walking around the streets until one guy told everyone that from looking into the glass sky for a few minutes, he was able to see some stars. As everyone started to look directly into the sky, their vision cleared up and saw what the man just saw: Our galaxy. This makes sense since Theia turned the sky into glass and it's a very powerful material, it was able to magnify the stars in space and present it to the citizens on the sky and have their vision fixed. Looks like Theia is right. The end!
