    Where is the evidence that life ever existed other than a cellular,
    DNA-based form? I understand your need to believe this, but
    I see not a shred of convincing evidence for your belief.

    Yes, this has been the rather fruitless guess for the last 100 years.
    Once again, I understand your need for imaginary entitites vastly
    simpler that what is observed to exist. But how can we falsify this claim?
