However, in the context of biology, intelligent design intentionally makes no mention of who or what the designer is, or what the potential motivations of that designer might be. Moreover, intelligent design takes a straightforward abductive reasoning approach towards design, arguing that design is simply an inference to the best explanation. When we see the amount of human thought and work that goes into creating complex artifacts such as smartphones, automobiles, and jet airplanes, then it is at least reasonable to believe biological organisms, which are far more sophisticated than any human artifact, require thoughtful design.
