What was daily life like for humans in the ice age?

I know this is a pretty vague question, basically I’m interested in languages and how they’ve changed over time and I know we don’t know anything about how humans communicated back then or what language change even would look like over some 20,000 years, but I’d be interested to know more about their beliefs, customs, general day to day life, diet and where most humans even lived back then. Thanks!
