It appears there may be a typo in your question. If you are referring to Galileo, he was an Italian physicist, mathematician, and astronomer who played a major role in the Scientific Revolution. Galileo made significant contributions to the fields of astronomy, physics, and the scientific method. His support for heliocentrism, the idea that the Earth revolves around the Sun, and his use of the telescope to observe the skies were groundbreaking in his time.

Why did Galileo make the telescope?
They didn't know what the telescope was. It was an accident. They called it the telescope, and tried to figure out what it did. They figured out that it can see far away. They (hans lippershey,and others) sold it to the military, and further more found out it could see farther. They looked so far they saw space, and they started inventing different galaxies.
