You are just advertising ignorance. Philosophy is neither opinion NOR fact - it's the study of how to tell the difference. 
Philosophy is the study of how to think so you arrive at the most correct answer possible.

A philosophy student, who does his work, will always be secure that his opinions are the closest to fact and truth that can ever exist - because his opinions are the only ones that obeyed the time-honoured techniques to ensuring just that outcome. For ensuring that fallacious reasoning did not derail them from the proper conclusions, for ensuring that the premise truly does support the conclusion.
Indeed, without philosophy there could BE no science - because the scientific method was developed by, and continuous to be improved by, philosophers.

In truth the relationship between science and philosophy is the same as that between engineering and science.
