The theories of originscreation and evolutionare not observable nor are they testable.
Evolution is both: we can both observe and test evolution. The existence of the common ancestor is inferred through the veracity of evolution. You don't have to physically see it happen to know it happened; I haven't physically seen my brain, but I daresay I have one.
Thus, they are religious.
Depends what you mean by 'religious'. 'Taken on faith' isn't enough, because people who believe in ghosts and aliens aren't necessarily religious, but still take such things on faith.
If you were to ask a Christian how God was created, he or she cannot tell you. It must be taken by faith. If you were to ask an atheist where the matter originated for the Big Bang, he or she cannot tell you. It must also be taken by faith. Either you believe in the beginning God or you believe in the beginning dirt. Neither can be considered science; they both are religions.
Not quite. Someone saying "I don't know" doesn't make them religious, nor does it make their beliefs faith-based beliefs. It may simply be that they really don't know. The Big Bang theory, for instance, is a very well-evidenced theory describing how the universe has developed and changed over the past 13.5 billion years (cheifly, by expanding from a singularity).
Where did that singularity come from?
Nobody knows.
BUT that doesn't make the Big Bang theory religious. One gap in human knowledge doesn't mean we should ring bells and sing praises to the LHC, or any such nonsense. It's not religious in the slightest - though it amuses me how the only people who attempt to charaterise scientific theories they don't like as 'religious' are themselves religious. Since when was 'faith' a dirty word?
Anyway. The Big Bang theory is well supported by the evidence, to the extent that there is no serious controversy within the scientific community as to its veracity. We are as confident that it is true as we are that atoms exist - which is to say, very confident indeed.
So the fact that we, at present, do not know where the singularity came from does not detract from the veracity of the Big Bang theory. Theories are
allowed to posit things. The less they posit the better (as per Occam's razor), but they're not forbidden under pain of becoming religions
In short: if a well-evidenced theory posits something, then the evidence for that theory is also evidence for the existence of that something. The evidence for evolution constitutes evidence for the universal common ancestor of life on Earth, and similarly with the Big Bang and the posited singularity, and similarly with General Relativity and the posited speed limit of the universe, etc etc.
Neither the theory of common descent nor the Big Bang theory are religious.
