The tiresome conflation of evolutionary theory with abiogenesis (with Big Bang side salad).
A favourite one, this, among the creationists who come here. Which always results in the critical thinkers going into petunias mode (read Douglas Adams in order to understand that reference). Since so many creationists are woefully ill-educated in this area, I shall now correct that deficit in their learning.
Evolutionary theory is a theory arising from biology, and its remit consists of explaining the observed diversity of the biosphere once living organisms exist. The origin of life is a separate question, and one which is covered by the theory of naturalistic abiogenesis, which is a theory arising from a different scientific discipline, namely organic chemistry. Learn this distinction before posting, otherwise you will simply be regarded as ignorant and ill-educated.
While we're at it, evolutionary theory does not consider questions about the origin of Planet Earth itself, nor does it consider questions about the origin of the universe. The first of these questions is covered by planetary accretion theory, the second by cosmology, both of which arise from physics. As a consequence of learning this, if you subsequently erect the tiresome conflation of evolutionary theory with the Big Bang or the origin of the Earth, be prepared to be laughed at.
As a corollary of the above, it is time to deal with:
 The Pasteur canard.
We have had several people erecting this canard here, and it usually takes the form of the erection of the statement "life does not come from non-life", usually with a badly cited reference to the work of Louis Pasteur. This particular piece of duplicitous apologetics, apart from being duplicitous, is also fatuous. The reason being that Louis Pasteur erected his "Law of Biogenesis" specifically for the purpose of refuting the mediaeval notion of spontaneous generation, a ridiculous notion which claimed that fully formed multicellular eukaryote organisms arose directly from dust or some similar inanimate medium. First, the modern theory of abiogenesis did not exist when Pasteur erected this law; second, the modern theory of abiogenesis does not postulate the sort of nonsense that abounded in mediaeval times (and which, incidentally, was accepted by supernaturalists in that era); and third, as a methodologically rigorous empiricist, Pasteur would wholeheartedly accept the large quantity of evidence provided by modern abiogenesis researchers if he were still alive.
