Irrespective of its truthfulness, astrology is really cool! I love learning about it. I also really like alchemy. It's kinda like looking at someone's fanfic AU. Of course 17th century guys were inventing cute lil alphabets, pretending they belonged to angels, and writing lil secret notes. Of course someone looked up at the sky and then invented a whole magic system about how the pictures affect our lives. Humans never change.

In fact things like Tarot and astrology can be used to ascribe meaning to some of the ways in which we behave - like, you can't tell the future objectively from it, but you can figure things out about your own current feelings based on what you gravitate to and what the results make you think about.
