...No, no it isn't. Logic has nothing to do with observation. Quite literally nothing. Logic is the study of arguments (and how arguments lead to one another). Or more specifically, logic is the study of inference, how conclusions can be made based on a series of premeses.
The common-sense idea of 'logic' is a fuzzy mixture of things being 'sensible' or 'reasonable'. But logic is just the study of arguments.
When we say something is illogical, we mean that there is no argument for it that is sound, valid, coherent and consistent (and a few other things).
Arguments can be divided into two catagories; a posteriori are empirical arguments, based on evidence and observation. This is the type of arguments that concerns science, and is probably what you're thinking of.
However, the second catagory is a priori, deductive arguments. This is the type of arguments that concerns mathematics, whereby arguments are considered self-evident. Take something like the argument 2+2=4. We don't need 'observation' or 'evidence' to show that this is true, it is true by the definition of '4'. It is true because it must be true. Other arguments take these self-evident truths and build upon them, combine them with other arguments, and all mathematical arguments are based on one or more self-evident truths (and sometimes, like in the case of Calculus, a non-self-evident premise).
It is this type of argument that concerns atheists. No, we cannot prove a posteriori that there is no God, because we haven't observed the entire Universe, so evidence of God might exist somewhere where we haven't looked.
But we can prove a priori that it is impossible for God to have certain qualities, because those qualities are either internally inconsistent (and therefore meaningless) or conflict with others (and therefore impossible).
There's quite a few of these arguments for the various supposed qualities of God (omnipotence, omnibenevolence, omniprescence, omniscience), and the end result is that it is impossible for a single God to have all of these qualities. This doesn't rule out the possibility of a radically different god, or multiple gods each with internally consistent qualities, but it doesn't leave any room for the 'Christian God'.
It is quite important that you don't confuse a priori with a posteriori.
Natural is that which affects this Universe, and supernatural (like the word suggests) is that with is 'beyond' or 'outside' this Universe; that which is not physical or material.
If you had evidence of God affecting the Universe (apart from creating it), then it quite possibly would. I don't know about 'the same', because it would require a little area of the Universe to be God's house or something, and that probably wouldn't work.
Scientists don't have bounds. Anything that affects this Universe is science. Science doesn't have any 'taboo' topics. The origins of human life, biology studies this. The origins of human morality, anthropology studies this. The origins of scientific method itself, science historians (and all scientists generally, the history and development of science is quite important to everyone) study this.
