It is only the increase in complexity that we don't believe in, and molecular research is increasingly supporting our position, as evidenced above.
How then do you explain the change from early chimp-like ancestor through several intermediates to modern humans? That's what the evidence suggests.
Is that a "loss of information" or complexity? Doesn't seem so to me.
(You do realize that the idea of a "fall" and a mandatory decline thereafter is a myth, don't you?)
Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.
