Micro-evolution does exist, adaptation within a species, however the evidence of millions of species arising from a speck of the simplest is simply not there from all I have studied, nothing close to conclusive on any level, this is what upsets me with the scientific community there simply is no honesty when it comes to this issue (and others as you alluded to in your post).
As far as whether the faith that I believe in christianity I do believe there is very good evidence for it being true, 2 very good books giving thus are The Case For Christ by Lee Strobel and Cold Case Christianity by J. Warner Wallace if u haven't read them and care to pursue further.
