There is no evidence that the planets or stars cause things to happen on Earth or of a cause-and-effect situation between the celestial bodies and life on earth. It just looks that way at first glance.
What is really happening is that celestial events and events on earth move to the same rhythm. There are different theories as to the source of this rhythm. Some say it is a fundamental force of nature, others say God, others say it is a divine universal intelligence.
