Because the earth is tilted with respect to the sun, so as we orbit the sun, different areas of the earth get more or less sun. That's the short and simple answer. There's other stuff that gets more complicated.

Seasons occur due to (1) tilt of the earth's axis and(2) orbital motion of the earth around the sun.
If the tilt is not there,(and the axis is perpendicular to the orbital plane), the day and the night would have equal time on the earth's surface for almost all places.The apparent north-south movement of the sun, will not be there and hence the summer and winter season will not occur.
If the tilt is there but the orbital motion is not there,then one hemisphere will always be pointing towards the sun always and that hemisphere will experience summer throughtout the year.
So,both the tilt and the orbital motion are combindly responsible for the seasons.

There are only seasons where the sun varies in its angle and proximity to the earth.
