"The planets each resonate with their own energy and who is to say that this energy does not add an individual signature to each of us at birth? A cosmic fingerprint "
I agree with rem, what energy are you talking about? The use of the word resonate implies that is has to do with sound, which I find very interesting. It is known that bodies give off sound, in fact, scientists found the lowest note in the universe not that long ago, something like 52 octaves below middle C. But the claim that this sound adds an individual signature to us is intriguing and unfoudned.
"who is to say that this energy does not add an individual signature to each of us at birth?"
Well firstly, you are making a claim here, you are implying that it does add an individual signature to each of us, more specifically, at birth. Who are you to make that claim? All skeptics are saying is that you haven't shown any good cause for this to be believed, and that you should show cause before they accept your claim. Skeptics don't work on the presumption of your claim being true, it needs to be demonstrated, otherwise the claim holds no more wait than the counter claim.
