Stated crudely, if you can’t demonstrate a function for something you shouldn’t make wild claims for functionality.
I find it more lkely that we are descended from ancestors that had a better sense of smell than that we are the ancestors of people with a better sense of smell.
I made no wild claims and what claims I did make I backed up far better than this:
“I find it more lkely that we are descended from ancestors that had a better sense of smell than that we are the ancestors of people with a better sense of smell.”
Ignorance of the function of some of genes in the olfactory system is a poor reason to assume evolution to be fact.
But as you will.
Remember my example of your computer?
