Eli5: How did we map the timeline of the big bang?

For example how did we know or come to assume that the Higgs field formed a trillionth of a second after it happened?

It all seems so specific and I think most topics in physics give unfulfilling answers and we’re just supposed to go with it. Thank you and sorry if I sound like an ignorant fool

Mathematic extrapolation and educated guesswork. We essentially ran a simulation of the universe and ran that simulation backwards and found that it all seems to come from one extremely small, dense point that exploded.
