Well that one is terrible and also, really? there are starving people and kids dying of disease and you think god is making sure you get a parking spot??!!
Also, “because there MUST be” (because I need a simple explanation).
I also would suggest the argument that “the human eye is a perfect creation” - asserted by someone wearing glasses!

The worst argument for creation: "You can't prove that He doesn't exist."

"God must exist because everything has an opposite, including the devil."

Erm... this may surprise you, but I don't believe in the devil either!

If I thought really hard and long, there is a possibility that I could come close... but I think yours is a winner.

The world is too complicated to have came into existence by natural causes. I’m ashamed to say this, but the argument has gotten so bad because I was so tired of hearing this person coming up with every pull it out of your ass answers, I actually came clean in a fit of rage and told her how much I hated her and how I once wished I could take an axe and put it to her head for trying to brainwash people with her crap and making them think her belief was the only way a person could be saved from some damn eternal in the lake of fire.

If there was a big bang, than there must have been a big banger and that is god.

The beauty around us... someone had to create it...
