Bill Maher says God is a "psychotic mass murderer".

Bill Maher expresses big problems with God in a profane diatribe.

Late night comedian Bill Maher expressed disbelief Friday that 60 percent of Americans are “stupid” enough to believe the tale of Noah’s ark is literally true and questioned why individuals worship God, who he described as a “psychotic mass murderer.”

“Isn’t life hard enough without making s*** up out of thin air to f*** with yourself?” he asked.

Maher — who is atheist and produced an anti-religion film years ago — said he believes that the tale of Noah’s ark is not only false, but also “immoral.”

“It’s about a psychotic mass murderer who gets away with it and his name is God.”
