Tautology – Faith itself can neither be proved nor disproved because, by its very definition, it does not require evidence or reason.
Appeals to emotion – “I can feel a presence” “But don’t you know God loves you!” “God is love”
Appeals to consequences – “If God doesn’t exist, where do we get our moral values from?” “If God doesn’t exist then I won’t get to live forever in an afterlife” “If God doesn’t exist, chaos will reign”
Arguments from ignorance – “We can’t explain consciousness/evolution/what happened before the big bang, therefore God did it”
This is one of better discussions that I have seen so far.
