How was the zodiac created?

Answer 1

As people tried to make sense of the night sky, they thought they saw figures in certain groups of stars. These people must have have good imaginations, because most of the figures don't look anything like the things they're named for.

In the course of a year, the Sun appeared to pass through some of these figures (You can't actually see this happen because the light of the Sun washes out all the other stars, but men could calculate when this must be happening.) and by coincidence or design, all of these figures were named for animals, so they collectively became the zodiac, after the Greek word, zoon, which means "animal."

The pseudoscience of Astrology developed to keep track of the position of the Sun (and Moon) relative to these animals. There had been eleven of them, but to make a even twelve, the claws of the Scorpion (one of the few that actually looked somewhat like its name) were redesignated as the Scales, so there's that one non-animal now.

Answer 2

Go outdoors. Look up at the sky. See all the stuff up there? What is it, where did it come from, why does it seem to move? That was the start of astronomy. long before there were telescopes.
