Faith: "belief that is not based on proof." (Dictionary.com)
Blind faith is just an extreme example. That's why we literally add a qualifier to it - "blind" faith.
You have no rational basis or tangible evidence for believing that something spontaneously comes from nothing, that life comes from non-life, that order comes from chaos, that reason comes from non-reason.
In fact, all our sense evidence and life experience shows those beliefs can't be true.
That's why I can't have the kind of faith it takes to be an atheist. It requires a belief in miracles.
