in the Legend of Satan, the biblical god said Adam and Eve would die that very day if they ate of the fruit. The snake said they would absolutely not die. Adam and Eve did not die that day, as the god told them, so Satan did not lie, the biblical god did. No other judeo christian religion (that I'm aware of) believes in that one day equals 1000 years nonsense, so how can they support the lie that this biblical god told them? This story was always one of the ones I never did get.
If you want a really good laugh about it all, read Good Omens by Neil Gaiman, hilarious book about what happens if the devil isn't quite as bad as he's painted, and god's not quite as good as he's given credit for. Oh yea, and the plot twist is that the anti-christ is born but he and another baby get mixed up in the hospital. Funny as all "hell"...
