harris or anybody,

what in science or nature would make one lean towards a conclusion that there is in fact no higher power/being than humans? the fact that humans would want to contact it, does not mean that it would in fact contact us if it existed.

the fact that some people do wacky things in the name of this power does mean it does not exist. the fact that some followers of this "theory" claim to have full understanding of it but really don't, does not mean it does not exist.
d
what in science or nature would suggest that this higher power does in fact NOT exist and is not behind evolution? what would make this any less viable of a theory than the big bang or any other?

or is it just personal opinion that concludes so surely that it is not viable?
