A conservative columnist, Ben Shapiro, tweeted that Obama is a "militant atheist" and added, "Unreal that Obama doesn't mention God in Thanksgiving message...to whom does he think we are giving thanks?"
Dana Perino, former White House Press Secretary for George W. Bush, argued that if you review the last three presidencies, God is usually mentioned. However, it does happen from time to time that God is left to of the the address. God was not included in President Bush's last Thanksgiving address. It depends on the speech writer.
