Why did the bible god make all the really fun stuff sinful?

Here's a clue for you and all. Lucifer was the lord of light, the highest archangel. He didn't change his name to Satan. The Christian writers did. Just as they made snakes and serpents tempters, to discourage belly dancing and goddess worship. Xians' bible rewrites history. They take some grains of truth, and flip them or camouflage them with some falsehoods, and we all know the creepy feeling that our minds have been scrood with and something "isn't right". Then they call that creepy feeling that they imposed on us, the result of 'original sin' to seemingly corroborate their lies.
