Darkness meaning sin.
"Sin" meaing those activites you don't agree with. I fail to see your point. In the absence of your initial assumptions - a god exists who sets moral codes - what does sin mean?
the answer is, it's meaningless. Does that mean I advocate no morals? to the contrary. By considering what does the most good for the most people, I can establish moral imperatives without recourse to supernatural entities.
What evidence points to a design without a designer?
Well, of course you can't have design without a designer. That would be a contradiction in terms. But there's plenty of evidence for function without design, for instance genetic programming techniques. Function and design aren't the same. It is possible to have function without design, just as you can have designs with no function.
Over 40 million babies only in America murdered in the womb. Yet they say it's not living. Billions of dollars are spent in killing ourselves with tobacco, alcohol and drugs. Billions of dollars are spent on pornography. Murders everyday all over the world. Gay-pride parades. You see "God Bless America" displayed at strip bars.
If they're in the womb, they're not, by definition, babies. Prior to exposure to language, I'm not even sure they're human. (of course, what constitutes "human" is a very open-ended question.) Nobody says they're not alive. But killing living things isn't always wrong (I assume you use soap and disinfectants?) Humans have a right to mess with their bodies because bodies are property. (Your own property, of course.) Pornography isn't wrong. It serves a very human purpose. Murders happen, which sucks. Some gay people are proud of the advances their community has made in securing basic human rights for themselves, so they're entitled to celebrate their victory. Strip bars have a First Amendment right to exist. If they're thankful for that right, why shouldn't they say so?
All these things sound bad to you, but that's your own opinion, not a universal truth. Otherwise why would so many people disagree with you?
When were taught evolution there is no accountability to the Sovereign Creator.
I guarantee you, this has never appeared in any scientific textbook at any school or university. No one has ever been taught this. if they reached this conclusion, they did so on their own, not as part of some brainwashing. If it's a rational conclusion to reach from the evidence, however, maybe that says something about your god?
