Is there anything wrong with having a faith?

Depends, Deni. You follow what is considered to be the core philosophy of what science is and as it extends towards atheism into what is more or less the standard atheism that people of that inclination tend to adopt.

There is, however, a form of atheism that eschews the sense of humility and replaces with almost dogmatic certainty in the power and scope of science and its ability to describe and prescribe for how the universe and its denizens operate.

This would be what some have called New Atheism, of its most widely read proponents are Richard Dawkins and Christopher Hitchens. Not only are they critics of religion, but they seek to supplant religion as the overarching authority which also includes morality, for some odd reason. Unfortunately, this mode of atheism has proven attractive and though still a minority, its numbers have given it enough voice to become the image of what most people "think" atheism is today.

Jam it back in, in the dark.
