If you're going to criticize astrology on astronomical grounds, you should at least learn enough of the astronomical basis of astrology to understand how to criticize it.
In this case, there's 12 astrological signs because the ecliptic passes through 12 constellations. (Actually, there's an interesting discussion about Ophiuchus, but this is where it's helpful to know that the constellations aren't well-fixed in divided space, IAU's process of doing so notwithstanding, and for astrological purposes, the ecliptic is instead divided into 12 equal-sized regions, each one labeled with a constellation)
