Can life start by itself?
There is no scientific evidence
that non-living matter spontaneously transforms into living matter (called abiogenesis, or spontaneous generation).
Intelligent researchers (at laboratories all over the world) using complex equipment and all the right ingredients, have failed every time
to demonstrate abiogenesis.
The more they research even the simplest living cells, the more complex they discover them to be.
The 1950s Miller/Urey experiments never achieved any living cells.
They used ammonia NH3
, water H2
O, methane CH4
and hydrogen H2
and subjected the mixture to heat and sparks.
They never got any living matter (usually: 85% tar, 13% carbolic acid, 2% amino acids and other chemicals). When oxygen was used in the gas mixture, they got no amino acids at all.
The production of some amino acids (the building blocks of proteins) is not the same as living matter.
In nature, amino acids exist in both left-hand (50%) and right-hand (50%) configurations. Living cells only have left-handed amino acids.
Evolution cannot even get started, as abiogenesis is impossible.
Life can only come from life.
The complexity of living matter:
Paul Davies, author of The Goldilocks Enigma:
"Biological organisms are immensely complex - far more complex than Paley could have realized.
To a physicist, they look nothing short of miraculous.
The many and diverse components function together in a coherent and amazingly orchestrated manner.
The living cell contains minuscule pumps, levers, motors, rotors, turbines, propellers, scissors, and many other instruments familiar from a human workshop, all of them exquisite examples of nanotechnology.
The entire assemblage runs itself with great efficiency, sometimes autonomously, sometimes in collaboration with other cells through a sophisticated network of intercellular communication based on chemical signaling.
The command and control functions of the cell are encoded in its DNA database, which implements instructions through intermediary molecules using an optimal mathematical code to convert software instructions into hardware products with customized functionality.
And this is just one cell.
In a larger organism, vastly many cells get together and cooperate to form organs such as eyes, ears, brains, livers, and kidneys, many of them immensely elaborate in their structure and function.
The human brain alone has more cells than there are stars in the Milky Way galaxy.
So it all adds up to a package of marvels that boggles the mind.
The total lack of any kind of experimental evidence leading to the re-creation of life; not to mention the spontaneous emergence of life... is the most humiliating embarrassment to the proponents of naturalism and the whole so-called 'scientific establishment' around it... because it undermines the worldview of anyone who wants naturalism to be true."
Answer: Life cannot start by itself.
