I agree. I actually think that is a very common thought, at least from what I have seen with my colleagues who are mostly scientists in engineering and biotech. It could be because of our background but the kind of complexity and seemingly genius engineering solutions in some biological systems just boggle the mind and make us question how it happened. We often handwave them with evolution and sure we can come up with some ideas of how it actually evolved but at some point I personally felt some explanations we got became too contrived and overly convenient and nearly unfalsifiable...

To be honest though, I still don't think a creator is absolutely necessary. But I also think there is nothing wrong with the idea that there is one. I just personally don't think this creator, if exist, would belong to any of the major religion out there.
