Verifying truth in science - is evolution faith-based?

I work for a software company. Our deveopers don't have know how transistors work or about electron potential wells to make our products work.Similarly, things like anti-biotics just work! Which should be proof enough that evolution is solid.The proof is in the pudding!

I apologize for going a bit off-topic here but I think this should be corrected:Macro-evolution is not a THEORY. Macro-evolution is simply a term used by scientists to classify large scale evolutionary changes.There is one theory of evolution and it is active now and can be evalutated and experimented against.If you want an example of things that are hard to experiment against gravity is a good one. So are many other things in theoretical physics. Evolution is easy to experiment against because it is occuring constantly all around us.I don't think that it requires much faith to believe in evolution because it simply works. Anti-biotics and modern agriculture are enough proof for me.Similar to how this computer makes me pretty confident that our electro-magnetic theories present a useful model.
