As others have answered, due to the axial tilt of the earth.
FYI, neither polar region has "6 months of day and 6 months of night". Each has actual day/night periods during the spring and autumn. The constant night/day periods only happen during the polar winters/summers and don't extend for more than a few weeks from the solstices.

As most responders have said, it is due to the earth's tilt of it's axis.
To see this for yourself, take a flashlight to your school's library or town's public library. Locate a globe; there should be one for public reference. Shine the light on the globe from the side as nearly level to the globe as you can; standing a few feet away is better than standing close. Notice the light falling on the south pole (Antarctica). Now walk around the globe, keeping the light shining on the globe. Notice how the light falls on Antarctica. It will go from dark to light and back. You have just simulated a year of the earth's travel around the sun. Half the year the south pole was in darkness; the other half in light.
The same thing holds true - but opposite - for the North Pole. When the south pole is dark, the north pole is light.

Earth's axial tilt of 23.5 degrees.
For 6 months out of the year, the Antarctic pole faces the Sun, and for the remainder, it faces away!

Since the earth's axis is tilted, Antarctica is pointed away from the sun for half of the year.

Due to the tilt of the axis and the revolution of earth around the sun.Both are responsible.

Because of the location on the earth.
