Some people will point out that man-made objects are clearly designed and made by intelligent minds, and argue by analogy that living organisms therefore must also be designed - usually citing the complexity and organisation in living organisms as evidence of that intelligent design.
Let's think about what intelligence means. I think it means the ability to come up with lots of different ideas, different possibilities, different solutions to problems, and figure out what works best. When we are babies, our actions are random and unplanned - we gradually learn by trial and error how to move, how to get what we want, how to avoid getting hurt and so on. As adults, we have a lot of experience to draw on so we don't need to try everything out to know what will happen - the trial and error often goes on in our minds, but we still do it, even if a lot of it is automatic.
So, when someone designs something, they go through this trial and error process, some of it in practice and some just mentally, to decide what will work best for what they want to achieve - an attractive design, an effective product, a big profit, or whatever. The smartest people are the ones who have the most varied and original ideas, and are most successful at choosing the best ones.
Now, notice the similarity with evolution: Random genetic mutation provides the different possibilities, the different solutions, and unthinking natural selection determines what works and what does not - i.e. a mutation which allows the individual which carries it to more reproductively successful will tend to be preserved and proliferate in the population, and one which is disadvantageous will tend to be lost, simply because the individual is never born, or dies before breeding, or breeds less successfully.
So in both cases - human design and evolution - the same factors of variation and selection are at work. That's why both phenomena are capable of producing complexity, and that's also why (I suggest) some people mistakenly feel that intelligence must be involved in both cases.
