Although no definitive answer has been provided to the origin of life, the vast majority of scientific data seems to support the ideas that, under appropriate chemical and thermodynamic conditions, a number of simple molecules tend to follow a self-organizing and self-replicating path towards growing complexity, in some sort of slow molecular evolutionary process which, over time, gives rise to the organic chemistry that we find today in almost all living organisms. Of course that many of the details of this process are still under active research, but the general idea that biochemistry and biological structures (like cell organelles) can very well emerge from simple precursors evolving under adequate conditions is the common thread joining together the various lines of research.

You extend the problem of origin to the origin of the universe itself, which I consider to be a rather distinct matter. While observations seem to be consistent with an infinitely dense and pointlike origin to the universe (the big bang singularity), several questions remain essentially unanswered. For example, was there something before the big bang? What brought about such extreme conditions at the beginning? Is the singularity real or just a mathematical artifact? How to understand the singularity if the laws of physics break down at that point?
