No one knows how the universe started, that is why they are researching it and need a unified theory with QM and cosmology.
We do know it had a beginning which isn't what it looks like today. We do know its expanding as well.
Explanation of how the Universe came into being from nothing.
An explanation about how the Universe came into being from nothing. Hopefully an explanation that you CAN wrap your head around. And because protons and electrons can pop into being all the time, the Universe has made this 'something from nothing' transition without breaking any of the known laws of nature.
Lawrence M. Krauss || A Universe from Nothing || Radcliffe Institute
The question "Why is there something rather than nothing?" has been asked for millennia by people who argue for a creator of our universe. Taking a trip back to the beginning of the beginning and the end of the end—and reviewing the remarkable developments in cosmology and particle physics over the past 40 years that have revolutionized our picture of the universe—Lawrence M. Krauss explores the discoveries that have revolutionized our understanding of both nothing and something. It has become clear that not only can our universe naturally arise from nothing, without supernatural shenanigans, but that it probably did."
Remember though in physics there is no such thing as No-Thing.
Also remember we can go back in Planck time to the beginning and then the math breaks down to nonsense.
Did Cosmic Inflation Really Jump-Start the Universe? (Kavli Hangout)

The oldest light in the universe, the cosmic microwave background, is a fossil from the Big Bang that fills every square inch of the sky. It provides a glimpse of what the universe looked like nearly 14 billion years ago, and can shed light on its evolution and how much dark matter and dark energy the universe contains.
Recently, two high-profile experiments released new
data
and analysis of this early light. Researchers working on the Planck satellite — which detects distant light from its orbit 930,000 miles above Earth —
released new maps of the cosmic microwave background. These maps seem to support the theory of cosmic inflation, which posits that the universe underwent an enormous expansion in the moments following the Big Bang. During that time, space grew monumentally, swelling from smaller than a proton to an enormity that defies comprehension.
Did Cosmic Inflation Really Jump-Start the Universe?

There was no carbon, when the universe began in the Big Bang, about 15 billion years ago. It was so hot, that all the matter would have been in the form of particles, called protons and neutrons. There would initially have been equal numbers of protons and neutrons. However, as the universe expanded, it would have cooled. About a minute after the Big Bang, the temperature would have fallen to about a billion degrees, about a hundred times the temperature in the Sun. At this temperature, the neutrons will start to decay into more protons. If this had been all that happened, all the matter in the universe would have ended up as the simplest element, hydrogen, whose nucleus consists of a single proton. However, some of the neutrons collided with protons, and stuck together to form the next simplest element, helium, whose nucleus consists of two protons and two neutrons. But no heavier elements, like carbon or oxygen, would have been formed in the early universe. It is difficult to imagine that one could build a living system, out of just hydrogen and helium, and anyway the early universe was still far too hot for atoms to combine into molecules.
The universe would have continued to expand, and cool. But some regions would have had slightly higher densities than others. The gravitational attraction of the extra matter in those regions, would slow down their expansion, and eventually stop it. Instead, they would collapse to form galaxies and stars, starting from about two billion years after the Big Bang. Some of the early stars would have been more massive than our Sun.
They would have been hotter than the Sun, and would have burnt the original hydrogen and helium, into heavier elements, such as carbon, oxygen, and iron. This could have taken only a few hundred million years. After that, some of the stars would have exploded as supernovas, and scattered the heavy elements back into space, to form the raw material for later generations of stars.
Life in the Universe - Stephen Hawking
"You seem to not understand what is being said to you.....I am not interested in pretend simulated conceptualizations, be they mathematical, visual, aural, verbal, symbolic, etc., I want proof as in making non living matter alive. Understood?
I showed how it is possible for the life to come from organic matter and you made no comment. I don't think you watch the videos and who that expert was on it.
Regardless, the early earth was extremely hostile to life in fact it would not have been able to survive,
no Van Allen belts, so radiation would fry everything, as well as the planet being hit by asteroids and volcanic activity, until things settled down and cooled. We also know Cynobacteria created the oxygen atmosphere we have today.
"Maybe so, but your limited belief as to what defines life is not one I would limit myself to....it's a bit like anthropomorphism, but extended to some of the lower kingdoms of nature...."
I don't believe rocks and gas and dust are conscious or intelligent or the Earth or sun or the universe. If you have something to prove that I am all ears, other then you just believe it.
An asteroid hits the Earth, Moon, Jupiter, Mars or what ever because they are in the path. I don't think all the craters on the moon were put there by something conscious or intelligent. Billions of things are colliding in space everyday if not a number no one could really grasp in the whole universe.
We see other solar systems forming now and know the process.
By what mechanism would the sun have cosmic awareness? Your saying its aware of itself? How does that work?
We only know of life on one planet right now, although good chance there are others. Perhaps some made from silicon.
No worries on the last items.
