Creationists/Intelligent Design proponents, how do you explain goose bumps?

Goose bumps are caused by the erector pili muscles, the tiny muscles that are connected to each hair follicle and the skin. When they contract, a "goosebump" forms, causing the hair around it to stand erect.

In nature, the purpose of "hair raising" is to make an animal appear larger, and hence more fierce to it's opponent. Of course, human body hair is far too sparse to create any visual threat, so goosebumps are essentially useless to us.

It has been argued that more primitive versions of man had significantly more hair than we do, which would explain the vestigial presence of them in modern humans.

So which makes sense?

Humans have vestigial goosebumps because we descended from a primitive hominid that once used them for survival...

or

God made goosebumps in animals as a SPECIFIC means for their survival, and then copied them IDENTICALLY on humans, even though they serve absolutely no useful purpose for our survival.

Obviously you believe in evolution. So . . . if you believe goosebumps serve absolutely no useful purpose for our survival then why do we still get them? If something isn't useful according to the evolution theory it eventually stops being reproduced you dummy.Therefore THERE MUST BE A GOD who means for us to have those goosebumps. Goosebumps are something you experience when something touches your soul (in addition to being cold).
