Matter into living organisms? Again you just have to accept that after the Big Bang and the expansion of the universe, material (atom and molecules of all possible elements) were interacting with each other. The interaction with unique elements caused cells to form. Cells began interacting with other unique cells, other material, itself, etc...
This caused bacteria, organisms, etc to start forming.
Now you're going to have to accept that (in general) living things... in this case bacteria, organisms, etc... want to survive. This need to survive caused evolution into well... Take a look around.
I wouldn't say sand or rock... think smalllllll and no, it was not all of a sudden.
One theory is the the RNA world hypothesis, which proposes that life based on ribonucleic acid (RNA) predates the current world of life based on deoxyribonucleic acid (DNA), RNA and protein. RNA is able to both store genetic information, like DNA, and catalyze chemical reactions, like an enzyme protein. It may therefore have supported pre-cellular life and been the first step in the evolution of cellular life.
RNA and DNA are made up of nnucleotides, which again are composed of elements from the periodic table. In e.g carbon, oxygen, nitrogen, hydrogen and phosphorous, all element readily available a the planets early days. Scientist have been able to create short sequences of RNA in a simulated environment of early-earth.
The RNA world is proposed to have evolved into the DNA, RNA and protein world of today. DNA is thought to have taken over the role of data storage due to its increased stability, while proteins, through a greater variety of monomers (amino acids), replaced RNA's role in specialized biocatalysis. The RNA world hypothesis suggests that RNA in modern cells is an evolutionary remnant of the RNA world.
