Purpose of eyebrows?
If God made everything for a reason, why do we have eyebrows?
In general those are difficult questions, because some things may have made
for a reason, but retained after the reason was gone. But for eyebrows, I can think
of two reasons that are still valid. First, along with eyelashes, they keep dirt from
falling into the eyes. Second, they participate in facial expressions which are major
forms of communication between people. This can be essential for life.
