The first living things on Earth are thought to be single cell prokaryotes. The oldest ancient fossil microbe-like objects are dated to be 3.5 Ga (billion years old), just a few hundred million years younger than Earth itself.[1][2] By 2.4 Ga, the ratio of stable isotopes of carbon, iron and sulfur shows the action of living things on inorganic minerals and sediments[3][4] and molecular biomarkers indicate photosynthesis, demonstrating that life on Earth was widespread by this time.[5][6]
On the other hand, the exact sequence of chemical events that led to the first nucleic acids is not known. Several hypotheses about early life have been proposed, most notably the iron-sulfur world theory (metabolism without genetics) and the RNA world hypothesis (RNA life-forms).

What can we really know about origins of the universe and life?

In addition to these many molecules, which would include the large and complex protein, DNA and RNA molecules, each with up to several hundred subunits arranged in a precise sequence, the origin of life would require many complex and dynamically functional structures, such as membranes, ribosomes, mitochondria (or energy-producing complexes of some kind), etc. Furthermore, life requires marvelous coordination in time and space, with many regulatory mechanisms. To believe that all of this came about by mere chemical and physical processes, does indeed constitute an immense exercise of faith.
If the primitive earth atmosphere contained a significant quantity of oxygen, however, an evolutionary origin of life would have been thermodynamically impossible, since all substances would have been oxidized to carbon dioxide, water, nitrogen, and other oxidized products, leaving no organic chemical compounds to serve as precursors for biochemical evolution. Evolutionists are thus forced to assume, a priori, that the primitive earth atmosphere contained no oxygen, but rather contained hydrogen, and that carbon existed mainly in the form of methane and/or carbon monoxide.
Even some evolutionists have found difficulties with these assumptions, however. Brinkman has maintained, for example, that a high rate of photolysis of atmospheric water vapor by ultraviolet light would have generated a significant quantity of oxygen very early in the earth's history,29 and Davidson has stated his conviction that there is no evidence that the atmosphere ever differed greatly from that of the present.30 If this is so, then a naturalistic origin of life could be eliminated without further discussion.

First and foremost, we now have concrete evidence for photosynthetic life suddenly appearing on earth, as soon as water appeared on the earth, in the oldest sedimentary rocks ever found on earth.

It is commonly presumed in many grade school textbooks that life slowly arose in a primordial ocean of pre-biotic soup. Yet, there is absolutely no hard evidence, such as chemical signatures in the geologic record, indicating that a ocean of this pre-biotic soup ever existed. "Accordingly, Abelson(1966), Hull(1960), Sillen(1965), and many others have criticized the hypothesis that the primitive ocean, unlike the contemporary ocean, was a "thick soup" containing all of the micromolecules required for the next stage of molecular evolution. The concept of a primitive "thick soup" or "primordial broth" is one of the most persistent ideas at the same time that is most strongly contraindicated by thermodynamic reasoning and by lack of experimental support." - Sidney Fox, Klaus Dose on page 37 in Molecular Evolution and the Origin of Life.
