What I, as a scientist, believe (for example, evolution) I believe?

Does "what I, as a scientist, believe (for example, evolution) I believe" mean " I believe what I, as a scientist, believe (for example, evolution)"?

Background info:

Fundamentalists know they are right because they have read the
truth in a holy book and they know, in advance, that nothing will
budge them from their belief. The truth of the holy book is an
axiom, not the end product of a process of reasoning. The book is
true, and if the evidence seems to contradict it, it is the evidence
that must be thrown out, not the book. By contrast, what I, as a
scientist, believe (for example, evolution) I believe not because of
reading a holy book but because I have studied the evidence. It
really is a very different matter. Books about evolution are believed
not because they are holy. They are believed because they present
overwhelming quantities of mutually buttressed evidence. In
principle, any reader can go and check that evidence. When a
science book is wrong, somebody eventually discovers the mistake
and it is corrected in subsequent books. That conspicuously doesn't
happen with holy books.
