I hate to sound mean but your ignorance is profound. First off science has never and most likely never will prove anything beyond a doubt. Not even gravity is proven. You want proof go to mathematics. What science can do is use evidence and observation to explain the world around us.
Also what does the fact that some scientists though the earth was flat hundreds of years ago have to do with modern science? The difference between science and religion is science changes and evolves over time as we come to understand our world more and more.
And please support your claim of the "prehistoric fish" with evidence. Just so you know your stating that there is no evolution is worthless unless you provide evidence to back it up.
