Absolutely not! Scent receptors and perception systems, olfactory
cells, and the genes that control them cannot exist in the absence of a

Creator Who made them. That Creator is God, “The Lord of the heavens
and the Earth and everything between them.” (Surat ash-Shu‘ara’: 24)

The Miraculous Connection in the Olfactory

Nerves
One very important property distinguishes olfactory nerve cells
from other neurons. Although the hundred billion or so neurons in the
brain cannot be replaced as long as we live, the millions of scent receptor

cells in the nose live for an average of 45 days. Those that die at the end
43
of that period are replaced by others. The site where new olfactory cells
arise is among the basal cells in the olfactory region. Basal cells work lit-
erally like a scent-cell factory, constantly and regularly producing new
ones.
