Difference between science and faith :
Science is firmly based on theories which are based on matter of fact.
Sometimes, science can be wrong as theories are disproved, prehaps as a result of technology and knowledge progression, however, the core principle of science is to discover facts.. or the truth.
Faith is firmly based on theories which can not proven/unproven.
Faith is simply that, believing in something that defies reason and sometimes it actually requires you to reject fact.. something that in certain cases, can be a life-threatening situation. Martin Luther King once said "Reason is the greatest enemy that faith has." I think that sums up my opinion on faith - if you believe in reason, you can't truly have faith.
So Im afraid, I agree with the general opinion that Ross' argument is garbage.. whilst science can be disproven and pluto very well may be exactly what he says... the science behind anything in life does not try to deceive you, it is based on actual facts. Knowing that, I can pick up an astromony book and believe it as fact quite easily.... If I pick up a bible, one of the first things to note is a talking snake and that the world is only around 6000 years old... both things go against logic, reason and every knowledgeable thing we know as humans.
