To separate the two strands of DNA.
Heating to ~95°C denatures the double helix by breaking the hydrogen bonds between base pairs, producing single-stranded templates for primer annealing and extension. (Note: some PCR kits also use a high-temperature step to activate "hot-start" polymerases, but the primary purpose of 95°C is denaturation.)
