How did space look like before the Big Bang?

This is a question that is impossible or almost impossible to answer as nobody was alive at that time. So there are a lot of theories. The most famous one and the one in which people believe in the most is the Big Bang; which consisted of an explosion that led into our universe that is constantly expanding. But I asked myself, what happened before that happened? There is one theory that consisted of a very tiny particle smaller than an atom that had a very high temperature. It started inflating until the size of a grapefruit and then exploded. After reading this, I wondered what was surrounding the mini particle and after the grapefruit, and the answer is simply nothing. Imagine vacuum bags, well what’s inside vacuum bags, nothing. For us, this is almost if not impossible to understand as we can not imagine emptiness/nothing/void. There is another theory that came to my attention. This theory was from Stephen Hawking. It consisted of before the Big Bang, events could not be measured, so it’s undefined. Time and space are not infinite, but they don’t have a beginning or an ending. Being the Big Bang a moment, not a place, time began when the Big Bang occurred.

There is another theory in which also a lot of people believe in. It’s called the Big Bounce. It’s like the Big Bang. It consists of a parallel identical universe that started decreasing until it got so small that it exploded and created a mirror universe. Therefore its name, it’s like if the universes are constantly bouncing. This leads us to think that we could be living in the first of all of the universes or in-universe 5.8 billion.

To conclude and to answer my question, I believe that these theories might be right although we’ll never know and never really understand. I think that we are not able to understand things like “nothing” or infinite. We cannot imagine something that existed always. And to answer my question, according to these theories, if the Big Bang created the universe; before the explosion occurred, space did not exist yet.
