Hi 328bera39, 322bera39, 624bera35, Harald.T.,
Human mind has learned overtime that any incident happening in universe has a scientific cause-effect relation. That’s why we ask what caused creation of earth, stars, galaxies; what caused creation of life; what caused earth & other planets revolve around Sun; and many more. We also keep on finding the answers as we know the fundamentals physical laws of the universe e.g. law of gravitation, general theory of relativity, quantum mechanics. These laws are all-time greatest inventions of human history which explains us the causes of all above questions and all causes of all other incidents in universe. Hence, mankind has taken physics in such a level that it explains any causes leading to any incident. Even we know our birth event of universe, called big bang.
Over 13 billion years ago, our universe started with a big inflation from an infinitesimally small point called singularity. That was the time when t=0. That was time when time started. That was time all physical matters & their basic building blocks e.g. electron, proton, neutron came into existence. That was time when all physical laws born.
So before finding what caused big bang we need to understand that entire TimeSpace and laws of universe started with bing bang moment. More we know about timespace, its science, its laws more we explain what caused incidents after big bang. But to understand what caused big bang, we need to know what was there before big bang. This is absolutely strange!!!!! Which is beyond the scope of science, laws, timespace, universe everything!!!!! Because nothing of these was there before big bang!!!! At-least at this stage science can’t answer this!!!!! Even if we think God has caused the big bang as he or she wanted to create Universe, I don’t find much meaning to it. Because we have still one unanswered question – what caused creation of god!!!!! And again we stuck, as cause effect relation is not closed!!!!!!

This is THE biggest question in cosmology. We can roll the film all the back to the starting point but what happens before the Big Bang is a fundamental question we have yet to answer. Will we get to the answer ? I don’t know but one thing I do know is that approaching it with a scientific method will lead us to the answer. It easy to throw your hands up and say “somebody made it”……but who made the maker? One possible, explanation is that there have in fact been a number of bing bangs already and we’re just a product of the most recent one. That still leaves the question unanswered. But I’m happy with it unanswered in some ways…..it’s still a mystery and something to aim for.

I think we’ll never know! The actual first 300 million years after the Big Bang cannot be observed and the conditions of temperature just after the Big Bang are so extreme we cannot duplicate them in a laboratory. What actually happened may be impossible to study and remain just educated guesswork.
This doesn’t bother me as we have a whole Universe of mysteries to solve!

Where do we have evidence that the Big Bang happened about 13 billion years old, in my opinion it is impossible to know when this happened and how I believe a bang cannot cause life.
