Faith is defined as belief in something without evidence.
There is evidence for evolution. Objectively, evolution is not faith.
Also, Intelligent Design is not a theory close to challenging evolution, any more than my theory of invisible tentacles being the reason we're attached to the earth is competition for gravity. It has no foundation or reason behind it, and literally relies soley on faith. Give proof of an intelligent designer and then it can be counted as a legitimate theory. Until then, it's just a terrible mash up of religion and science, and it doesn't even have cool space marines to make it attractive.

Quote from WandereroftheDeep
Evolution is a fact unless proven otherwise, as is the case with all scientific theories.
Actually, this is incorrect. Evolution is not a 'fact', it is what it implies which is a theory. A theory is not a fact. A theory by definition is "a proposed explanation whose status is still conjectural and subject to experimentation, in contrast to well-established propositions that are regarded as reporting matters of actual fact."
You don't seem to understand what a scientific theory is. While it is called a "theory", it actually a fact. For example, the theory of gravity is confirmed. It is absolute fact that it exists. It's not a thought experiment or an idea. It's confirmed to the truest definition of the word.
Evolution is the same. It is accepted as truth.
