To be fair, there's no evidence, and no necessity, for a designer,
If there were, that designer would be inefficient to a brain-boggling degree, needing 14 bn years and maybe septillions of stars and their associated planets just to produce humans on one of those planets, no?
And it's not as if humans are such a brilliant idea if you're looking from the outside. Ever since they got smart enough to trash the earth, they've made a remarkably effective job of doing so, no?
If I were a superbeing with superpowers, and I thought humans were in some or other way valuable or important or useful enough to justify the effort, I'd have stepped in and prevented it from happening in the first place, way back when. That would certainly be the smart way of solving the problem, no?
