Copernicus vs Galileo

some people think that Copernicus is the best scientist because he came up with the idea of the Sun not orbiting the Earth and he also tested it out but he was too chicken to tell everyone. Some people think that Galileo was the best scientist because he tested out also but he put the nail on it

by telling everyone that it was fact and he also proved it.

Who do you think was the best scientist..........................
