The Witness lied...again.

The Witness is NOT the first knife. It just thinks it's that important. I read through Unveiling and I stumbled across this in Cambrian Explosion:

'Beings who deserve no thought:

Those who peddle the tired gotcha that all life hastens entropy. They are fatuous little nihilists who pretend to prefer no existence to a flawed one. They bore me."

Knowing what we know now this is pretty direct. The Witness was of no real significance.

It's just a spoiled brat.
