I believe in science for the most part, but even scientists get it wrong and sometimes (in fact quite often) and can't agree with each other about their results and quite often try to de-bunk each others research... 
There is quite a lack of discipline in certain sections of the scientific community these days and it mostly seems to come from the same old faces that you see time and time again on documentaries on the likes of the Discovery channel... 
Reckon myself some of these so called "Scientists" will do & say anything for their 15 minutes of fame... :rolleyes:
I think that you are mixing up the scientific community with the few scientists that appear on TV.
And yes, scientists try to "debunk" each others' work, because that's one of the most effective ways of attaining new knowledge. There are very few things that can be proven right off the bat (outside axiomatic systems like mathematics), but by setting up specific test cases to try and disprove theories you can rethink, remodel and learn a lot.
Scientists generally don't get things "wrong," either. Discoveries are presented as theories, models and data, and you'll rarely find any scientific research claiming to have attained absolute truth (because that notion in itself is scientifically unsound).
What we can expect from modern science, though, is a bunch of closer and increasingly accurate models of phenomena that would otherwise be incomprehensible to us.
Finally, science is not a system of belief. It should not be posed as if it was analogous or inherently opposed to personal faith, and you're not supposed to blindly accept scientific findings as truths.
