Um, no. Throughout my careers (notice the 's' there), I've worked with many things that at first glance appeared to have come from some kind of intelligence but when studied and probed will show that they are just the inevitable consequences of how the universe behaves.
For instance, there is nothing more prevalent than the universal law of accumulation. Things accumulate over time. If there is some kind of selective mechanism to choose which to accumulate and which to not accumulate, then over time we will have things with patterns.
If that doesn't make sense, try to look at it this way. It either is or isn't. If it's isn't, then it's not there and so you won't even think about it. If it is, then it's there and then you're gonna wonder why it's there in the first place.
