The line in panel 1 reminds me of a similar joke about God and some scientists:
Scientist: "Well God, me and the others were thinking, and we agreed that we're all really grateful to you for making the universe and humans and everything, but we don't really need you anymore. We can fly and cure anything and change the world around us. We can make our own miracles, so we don't need yours."
God: "Hmmm... okay, that seems fair. Tell you what: let's have a human-making contest. Whoever can make a human from dirt first wins, and the winner gets to be in charge of everything."
Scientist: "Sure, no problem!" *bends down to pick up some dirt*
God: "Ah ah ah. Sorry, but you've got to get your own dirt."
