The history of the universe: Big Bang to now in 10 easy steps

The history of the universe and how it evolved is broadly accepted as the Big Bang model, which states that the universe began as an incredibly hot, dense point roughly 13.7 billion years ago. So, how did the universe go from being fractions of an inch (a few millimeters) across to what it is today?

LOL. The first “step” is 380,000 years.

Way back on 1977, Weinberg published an entire book on “the first three minutes”.

More recently, we have found that “The inflationary epoch is believed to have lasted from 10^−36 seconds to between 10^−33 and 10^−32 seconds after the Big Bang.”

But since conditions at that time were outside anything we can physically model by some huge factor, why should we take any notice of the results of mathematical extrapolation?
