The Big Bang theory is not a theory of the creation of the universe. Full stop. Done. Call it. Burn that sentence into your brain. Say it before you go to sleep, and first thing when you wake up. The big bang theory is a model of the evolution of universe, tracing the evolution of the cosmos to its very earliest moments. And that's it. Don't try to stuff anything else into that framework. Just stop. Going back before 10^-36 seconds, we simply don't understand the nature of the universe. The Big Bang theory is fantastic at describing everything “after” that, but before it, we're a bit lost. Get this: At small enough scales, we don't even know if the word "before" even makes sense! At incredibly tiny scales (and I'm talking tinier than the tiniest thing you could possible imagine), the quantum nature of reality rears its ugly head at full strength, rendering our neat, orderly, friendly space-time into a broken jungle gym of loops and tangles and rusty spikes. Notions of intervals in time or space don't really apply at those scales. There are, of course, some ideas out there , models that attempt to describe what "ignited" or "seeded" the Big Bang, but at this stage, they're pure speculation. If these ideas can provide observational clues — for example, a special imprint on the Cosmic Microwave Background. So, at this moment, it’s impossible to say how Big Bang happened or what existed before
As I understand Big Bang cosmology and the inflationary theory, the two are distinct. The Big Bang indeed being a cosmogenic model, whereas the inflationary theory is cosmological. While the latter describes the evolution of the universe, the former is a suggestion for its creation, which doesn't specify the exact means by which this inception occurred, allowing for suggestions such as quantum fluctuations or the collision of membranes in string theory.
