Well, let's look at a simple thing, the Moon itself affects the tides of the ocean. And, it most likely affects menstrual and birth cycles. I know, I know, the experts say that it doesn't affect anyone. But, my eldest sister was a nurse in a delivery ward and she would tell you that things would pick up at a full moon.

I watch and post information about space weather. One of the theories that I have been following is that sun activity is linked to major earthquakes. The guy with the theory has been over 70% accurate in predicting the location of an upcoming earthquake out to 24 hours before it happens.

Another part of the space weather, is that it is pointing towards the ability to change the climate on the planets. Earth isn't the only planet experiencing global weather changes. Even Jupiter's huge storm has seen changes, which can't be touched by man-made global warming.

Another theory has tried to link the sun's activities with the downfall of empires. Nothing that strife increased right before the sun would go quiet and then the empire would fall. It is possible that the sun is affecting humans in more ways than just the extra radiation you get while flying.

So, with just these scientific studies we could assume that based on what is going on in the solar system and the galaxy as a whole, it is possible that alignments at birth could affect people down to a DNA level. There is so much we don't know about DNA.

On a religious side, even Christians would have to accept the fact that the Three Magi were astrologers and found Christ by following the signs from the stars in the sky.
