Was there life during the ice age

Absolutely! There was life on earth during all recorded ice ages and long before the oldest recorded ice age. If you were asking about the last ice age, the living things were mostly the same as now, except for some species strongly adapted to cold that went extinct about the end of that ice age (e.g. woolly mammoths). Modern stone age humans were on all continents except antarctica and south america through the last ice age.
