The author does not understand the notion of falsifiability. It is not necessary that we have the technology to discover the physical manifestation of memes right now for them to be a valid scientific hypothesis, only that in principle we can someday conduct tests that may potentially refute the hypothesis. This does not mean that memes do definitely exist. It just means that the proposal for their existence is scientific and rational, pending further investigation. On the other hand, the notion of faith in God is, by definition, not a falsifiable theory; no experiments can ever be done, even in principle, to disprove faith, since it is by definition an extra-rational concept that proposes you should accept its veracity without evidence, and indeed despite any evidence that it may not be true. This is an anti-scientific theory. The two proposals are thus fundamentally different in terms of how they -- on their own terms -- suggest you should evaluate their veracity. One is scientific (that is, falsifiable); the other is not.
