Kay Hans Lipphershey invented the telescope because he was a lensmaker. at the time his kids were playing outside when they discovered it, Hans didnt really create it it was his kids but he took the credit from them. people think that Galileo also created it but he did not. he took it a step further from Lipphersheys idea and just made it better. so they should both be credited. he created it also for the scientists and mathematicians in that time could study the planets and solar system
