I recently came into argument with an atheist regarding the origin of the universe. I told him that it is an unsolved problem in physics and in cosmonogy in particular. But he kept saying that it has already been confirmed by scientific evidence that "matter and the universe were created out of nothing by random fluctuations" citing these two statements below:
Inflation is today a part of the Standard Model of the Universe supported by the cosmic microwave background (CMB) and large scale structure (LSS) datasets. Inflation solves the horizon and flatness problems and naturally generates density fluctuations that seed LSS and CMB anisotropies, and tensor perturbations (primordial gravitational waves).

The inflation theory is a period of extremely rapid (exponential) expansion of the universe prior to the more gradual Big Bang expansion, during which time the energy density of the universe was dominated by a cosmological constant-type of vacuum energy that later decayed to produce the matter and radiation that fill the universe today.

I'm not really familiar with scientific jargon but I'm dubious if these statements especially the bolded part actually translate or mean "matter were created out of nothing by random fluctuations." Can anyone translate these statements in layman's terms?
