Read your words. You are making a very positive claim "It didn't happen by mindless chance." And you are making that claim without being able to provide one single atom of evidence for it -- not one, nothing, nil. Just "I don't know, so it must have been, right, eh, huh?"
Darwin -- and thousands of serious scientists since -- have been able to demonstrate an immense amount of how that "mindless chance" works (it's called "natural selection" but since you don't read, you'll just have to take that on faith). If I had the time (and the futile desire to try and teach the unteachable), I could provide millions of words very real science showing how it happened.
And you can provide -- well, frankly, nothing but "I don't understand it, so it can't have been that -- therefore I'm right." This is not intelligence.
