The geological record is consistent in showing life beginning with very simple forms, growing more complex as the eons passed.
How did it begin?
Abiogenesis is one idea, panspermia another and special creation.
This site lists 10 such "theories", except they are not confirmed scientific theories, just hypotheses at best, while divine creation is outside the scope of scientific inquiry.
So what, exactly, prevents you from reading & learning more about it?
JohnyBoy: "Today they no longer bother with the scientific testing and stick to endless speculation, which isn’t science."
What you call "speculation" others might name "brain-storming", an essential precursor to scientific hypotheses.
As for more recent experiments, This article from 2010 discusses several.
This article discusses Cech's experiments & findings in RNA.
Fox experiments in amino acids.
Miller-Urey revisited & updated
This 2009 article mentions experimental work of several scientists in the Origin of Life field, including Ellington, Venter, Joyce & Szostak.
This article takes a fairly pessimistic view, including this quote:
- "Since a single cell would appear to be the smallest unit that can be said to be alive, proteinoid microspheres may quite justifiably be called protocells, or, life.
These are just the early stages of these types of experiments.
There is every likelihood that within the next couple hundred years man will be able to create self-replicating life of varying forms from purely chemical and natural elements under laboratory conditions. --- Simon Ewins "
A "couple hundred years" sounds like there's much more they don't know than do.
And you disagree with what, exactly?
