What actually happens that causes non living matter to become living matter?

We don't know exactly how it occurred yet.

No, we are not making things up. Scientific theory is about creating the best explanation of a phenomenon form the evidence we have. Then you test that theory and if need readjust based on the new evidence.

1 of life's many mysteries & likely will

never be known the answer might be rooted

in our way of defining what is alive vs what

is not.

What is your evidence for non-living matter becoming living matter? All life, plant and animal, is propagated from living cells.

"A [sic] actual real solid answer" presents the 'fallacy of the single cause.' https://en.wikipedia.org/wiki/Fallacy_of_the_singl... Increase your tolerance for ambiguity. But, if you must have a single cause, it is time.

It seems that we have to have faith to believe that God created everything, and, alternatively, we have to have faith that life was accidentally created.

BECOMING ALIVE: Life might exist somewhere (perhaps on other planets around distant stars) that is not like the life that we know. It might be silicon-based or it might be an electric field. Life as we know it supposedly came into existence when lightning struck a pond creating amino acids. Somehow a skin was formed around the amino acid and the organism was able to eat to sustain itself and excrete waste.

PROCREATION: Life is supposed to require procreation. However, if life could be created from non-living matter, then other life could be created too. Therefore, an organism doesn't need to procreate to continue to exist. It would be quite a coincidence that the first organism that was spontaneously created also had the ability to procreate. I have to conclude, therefore, that many organisms can be spontaneously created that cannot procreate. When one such organism somehow obtains the ability to split in two (like an amoeba) it will eventually take over the world (or the part of the world that it is able to live in). From there, it might evolve into a creature with two sexes.

You don't much follow science, do you?

You need just eight ingredients: two proteins, three buffering agents, two types of fat molecule and some chemical energy. That is enough to create a flotilla of bouncing, pulsating blobs — rudimentary cell-like structures with some of the machinery necessary to divide on their own.

"I can't understand the science when people explain it" isn't the same thing as "They're wrong."
