I believe the correct answer is that we're not sure, but probably it was something that happened early in Earth's history - some massive collision with another planet. I can tell you why the earth stays tilted - the moon's gravity keeps it in (roughly) the same position. Without the moon, various effects of a large planet spinning would cause the earth to spin all over the place. However the angle of the tilt does vary slightly, between about 22 and 24.5 degrees, but this variation is very slow.
