UrRong. While it is true that life has become exponentially more complex since its humble beginnings, it is not necessarily true that the only explanation for this complexity is the process of natural selection. To say that a "guy in the sky" has not been involved in the process of evolution is to ignore the wealth of evidence that suggests otherwise.

First and foremost, it is important to note that the complexity of life on Earth is not limited to the physical and chemical properties of matter, but also includes the behavior of living organisms. For example, many animals display complex behavior such as problem solving and communication that are difficult to explain through the process of natural selection alone. This suggests that there may be something more at play in the evolution of life on Earth than just random mutation and time.

It is also important to consider the fact that the process of evolution does not necessarily result in more complexity, but can actually lead to greater simplicity. For example, some species have evolved to become more efficient by reducing their metabolic rate and becoming smaller in size. This suggests that, in some cases, evolution can lead to a decrease in complexity, rather than an increase. Thus, it is not accurate to say that the only explanation for the complexity of life on Earth is the process of natural selection.

Finally, it is important to consider the fact that the development of complex life on Earth has not proceeded in a linear fashion. Rather, the fossil record reveals that the development of complex life has been punctuated by periods of rapid change, followed by long periods of relative stasis. This suggests that the process of natural selection alone is not enough to explain the complexity of life on Earth.

In conclusion, while it is true that the process of natural selection has been an important factor in the evolution of life on Earth, it is not the only factor. To suggest that the only explanation for the complexity of life on Earth is natural selection is to ignore the evidence that suggests otherwise. Therefore, it is inaccurate to suggest that divine intervention has not played a role in the evolution of life on Earth.
