I've seen the lake of fire. Its not a volcano, its not on Earth and its horrid. I don't know what to say about timetraveling advanced humans, its certainly a possibility, but it still doesen't satisfy the first-mover theorem and I refuse to believe we exist because of an infinite regress. I have direct personal evidence of God at this point but I don't pretend to understand how he 'works'. I do expect we will be told when its acceptable.
