Why do fetuses have hair? Why do many scientists deny a Creator?

Why do babies grow hair before they are born which they later lose? Doesn’t this prove we have a common ancestor with apes?

This is the gist of an argument presented by Jerry Coyne. He mentions that hair keeps mammals warm, which is true. He points out that human babies have hair in the womb where they are not exposed to the cold, suggesting that this hair serves no purpose in humans. He then insists that the only way to understand this phenomenon is to believe that humans evolved from other mammals, implying the hair is an evolutionary leftover.

However, if we look closely at what this hair is, the timing of its appearance, and other related factors, this argument by Coyne is seen to be quite presumptuous.

Bystrova (2009) gives reasons for believing that this hair allows for sensory stimulation in utero that affects the growth rate of the baby. Additionally, this prenatal sensory stimulation is considered somewhat analogous to postnatal sensory input, as in a mother touching her baby, which is considered important for healthy development.

This points to a bigger question. Why do some scientists declare class warfare against anything that could possibly point to a Creator? While others are truly productive scientists? Productive scientists look at known details in living things and tend to assume that the structures and processes they observe have a function. This leads to improved understanding and medical advances. The argument by Coyne is not scientific and can be traced back to a philosophy, one intended to deny that there is a Creator.
