Drugs are usually intelligently design to be addictive. I don’t see your point.
If God doesn’t exist why do we have this predisposition? (you haven’t answered)
There is an innate predisposition to drug addiction,
whether a specific drug is "intelligently" (by who?)
or not.
There is an innate tendency toward violence.
I am pretty sure I said I dont know why
there would be an (apparent) predisposition to
believe in "god", or, to violence, or drug addiction,
for that matter.
We like puppies, probably because they trigger our
innate love for babies.
As babies, we have innate love for our parents.
The all powerful givers of life.
My guess is that the search for a "god" to fill that role
is, just that. The search, as an adult, for something
to fill the role t hat parents had.
Seems more likely than that there is a thing that is
greater than the universe, exists outside of time and
spacer, knows everything and can do anything.
Just my pov, if you are interested. If you want to see
the innate behaviours of people to be signs of god
thats fine.
