Darwin Dad
An atheist version of God father. Similar principles of the traditional version i.e chosen reliable friend or family member who will always be there for your offspring. Offering assistance and guidance in their upbringing, and just like the majority of traditional versions, never setting foot in a church!
Ben, as a fine upstanding fellow, and with me thinking the world might be a little better without religion, would you do me the honour of being Grace's Darwin Dad?
