Is there common sense in Science?

That would be one question among many that I would ask. Some others would be along the lines of a definition to Science. Is it the collection of facts to explain something? Is there room to add speculation in there?
The reason I ask is Darwinism and Intelligent design are two competing theories to our creation as a species. I do not understand why it has become so bitter on both sides that people of high academic standing loose their jobs over it.
Would it not make sense, under the solid definition of science, to gather all the facts before you draw any conclusion. Without concrete evidence from either side no one has the right to present their theory as being the correct one.
Therefore I am left to keep an open mind as to how we came to be. I have absolutely no time to be bitter about a theory that is incomplete. Maybe the people who make these arguments should spend their time more wisely, like actually gathering more facts, so they can truly answer the question.
