Which place is colder Antarctica or Siberia?

Siberia is colder than Antarctica. The coldest temperature ever recorded on Earth was −89.2 °C (−128.6 °F) at the Soviet Union's Vostok Station in Antarctica on July 21, 1983. However, the average temperature in Siberia is much lower than in Antarctica. The average temperature in Siberia is -25°C (-13°F), while the average temperature in Antarctica is -57°C (-70°F). This is because Siberia is a land mass, while Antarctica is a continent surrounded by ocean. The ocean helps to moderate the temperature in Antarctica, while the land mass of Siberia allows the temperature to drop much lower.
