If you can provide evidence for lack of design, I will surely understand it. Just claiming that things are not designed because they simply are not, is not an argument.

It's always like that for you, isn't it. Why should I provide evidence for things that are not designed? You are assuming that everything is designed for no reason, I'm not the one trying to prove god you are.
You shouldn't provide evidence for things not designed... for at least 2 reasons:
1. There aren't any, so you can't;
2. You should be spending all your time changing your heart to believe in God so that you can be saved.
All the things that mankind designs operate through the things of nature. Everything is designed. If it weren't, mankind couldn't design anything, because he uses nature in his designs. Either mankind desing including the nature he uses, or no design, not even of mankind.
Why? Because in mankind design, he uses nature. It's design or it isn't, both mankind and nature, because they are essentially the same at their core.

''Everything is designed. If it weren't, mankind couldn't design anything, because he uses nature in his designs'' What are these arguments lmao, you are desperate. If things weren't designed mankind couldn't design anything? Why, how does that work lol. A computer or a spoon aren't designed copying nature. Stop with this stupid shit.
